League of Legends Client Repair Guide
League of Legends Client Stuck Loading, Black Screen, or Reconnect Loop Fix
Separate Riot Client loading problems from champion-select reconnect loops, then repair the client, remove overlays, check compatibility settings, and collect logs safely.
Last updated: July 14, 2026
When the League of Legends client is stuck loading, shows a black screen after login, or keeps showing the Reconnect button after champion select, do not start by deleting random Riot folders. The correct fix depends on where the problem appears.
A Riot Client login loop is different from a League home-screen black screen. A reconnect loop after champion select is also different from in-game FPS drops or network lag. Use the first table to identify the exact failure point before repairing, reinstalling, or changing compatibility settings.
Fastest safe recovery order
Check Riot service status → fully close Riot Client and League processes → restart Windows → run Riot Client Full Repair → close overlays and recording tools → fix reconnect loop compatibility settings → check Fasoo, Citrix, and other conflicts → use clean boot → reinstall only at the end → collect Riot logs for support.
Do not treat every League launch issue the same way
If the patcher is stuck at 0 B/s, focus on download and storage. If League crashes during a match, focus on drivers, overlays, memory, and heat. This guide is for the client, black screen, and reconnect-loop path.

Separate the Problem Before Fixing It
| Where it fails | Likely category | Check first |
|---|---|---|
| Riot Client does not open | Leftover process, permissions, security block, or Riot service issue | Task Manager, restart, service status, and Windows Security history |
| Login works, but the client keeps loading | Client session, damaged files, service issue, or UI rendering problem | Full Repair, overlays, and graphics driver |
| Client home screen is black | UI rendering, overlay hook, graphics driver, or GPU switching | Close overlays and compare Windows graphics preference |
| Champion select finishes, then Reconnect repeats | Game executable compatibility, admin setting, or external software conflict | League of Legends.exe compatibility settings and known conflict tools |
| Update is stuck at 0 B/s or 0% | Download, storage, network, or patcher problem | Use an update/download troubleshooting path instead |
| Game starts, then crashes during a match | Driver, overlay, memory, temperature, or in-game crash | Use a crash and performance troubleshooting path instead |
Avoid deleting folders first
Riot folders can contain settings, Riot Client files, logs, and files for other Riot games. Use Full Repair and targeted checks before deleting folders or reinstalling the entire game.
1. Check Riot Service Status
When several players cannot log in, the client keeps loading, or matchmaking services are unavailable, check Riot’s official service-status page before changing your PC.
- Open Riot Games Service Status.
- Select League of Legends.
- Choose the correct region.
- Check login, game, and client service notices.
- Ask a friend in the same region whether the client works.
- If a service incident is active, wait instead of reinstalling.
Server problems are not fixed by local repair
If Riot reports an outage, avoid deleting folders or resetting network settings. Record the incident time and test again after the notice clears.
2. Fully Close Riot Client and League Processes
Closing the visible client window may leave Riot or League processes running. End the old session before repairing or launching again.
- Open the notification area near the Windows clock.
- Right-click Riot Client and exit it.
- Press Ctrl + Shift + Esc to open Task Manager.
- End clearly visible Riot Client, RiotClientServices, LeagueClient, or League of Legends processes.
- Do not end unrelated Windows services.
- Restart Windows.
- Launch Riot Client once after the restart.
Startup apps can reopen conflicts
If the issue returns after every reboot, review startup apps. Use the Windows 11 startup-app guide to disable unnecessary overlays, launchers, and recording tools.
3. Run Riot Client Full Repair
Riot’s Full Repair scans and repairs damaged or missing files. Use it before uninstalling League of Legends.
- Open Riot Client.
- Sign in.
- Open settings from the profile or gear area.
- Select League of Legends.
- Choose the repair or Full Repair option.
- Keep Riot Client open while the check runs.
- Restart Windows after the repair finishes.
- Launch League again and test the same step that previously failed.
Repair is safer than random cache deletion
A repair tool can replace missing or corrupted files without wiping unrelated Riot game data or personal settings first.
4. Fix Login Black Screen or Infinite Loading
If login succeeds but the League client window is black, blank, or stuck loading, check UI rendering conflicts before reinstalling.
- Close Discord Overlay, NVIDIA Overlay, AMD Overlay, Xbox Game Bar recording, and other screen-capture tools.
- Close stat trackers, companion apps, and overlay-based performance monitors.
- Install pending Windows updates.
- Update or cleanly reinstall the graphics driver only from NVIDIA, AMD, Intel, or the PC manufacturer.
- On laptops, compare Windows graphics preference for Riot Client and League.
- Restart Windows and launch Riot Client before reopening overlay tools.
Laptop GPU switching can matter
If a black screen started after a driver update, compare power-saving and high-performance GPU preference instead of assuming that one setting always works better.
5. Fix Reconnect Loop After Champion Select
When champion select completes but the game window does not open and the client only shows Reconnect, use the reconnect-loop path. Riot’s reconnect article highlights compatibility settings, administrator rights, debug memory dumps, Fasoo, and Citrix-related checks.
| Reconnect-loop clue | Likely area | Action |
|---|---|---|
| Game window never opens | Executable launch or compatibility setting | Check League of Legends.exe properties |
| Reconnect button appears immediately after champion select | Game executable did not start correctly | Disable compatibility mode and Run as administrator |
| Only happens on a work or school PC | Document security, remote workspace, or endpoint protection | Check Fasoo, Citrix, and IT-managed tools |
| Reinstalling did not fix it | External conflict, compatibility flag, or system configuration | Use clean boot and collect logs |
6. Disable Compatibility Mode and Run as Administrator
For reconnect loops after champion select, check the game executable settings rather than only the Riot Client shortcut.
- Open the League installation folder.
- Open the Game folder.
- The common path is C:\Riot Games\League of Legends\Game.
- Right-click League of Legends.exe.
- Select Properties.
- Open the Compatibility tab.
- Clear Run this program in compatibility mode.
- Clear Run this program as an administrator.
- Select Change settings for all users and check the same options there.
- Apply the change and restart Windows.
Riot Client admin launch and game executable settings are different
Testing Riot Client once as administrator is not the same as keeping League of Legends.exe permanently forced into administrator or compatibility mode.
7. Check Fasoo, Citrix, Overlays, and Security Tools
Riot’s reconnect guidance specifically calls out known software-conflict areas. Also check common tools that hook into graphics, input, documents, or remote work sessions.
- Fasoo or document-security software
- Citrix Workspace and related protection features
- Remote work, virtual workspace, or endpoint-security tools
- Discord, NVIDIA, AMD, Xbox Game Bar, and recording overlays
- Stat tracker, companion, and capture tools
- Macro, mouse, keyboard, RGB, or hardware-control software
- Third-party antivirus, firewall, and PC optimization tools
Do not remove work or school security software without approval
Fasoo, Citrix, and endpoint-security tools may be required by your organization. On a managed device, ask IT support before disabling or uninstalling them.
8. Use Clean Boot Safely
Clean boot helps identify whether a non-Microsoft service or startup app is causing the stuck client or reconnect loop. It is a test state, not a permanent setup.
- Take screenshots of your enabled startup apps and services.
- Press Windows + R.
- Type msconfig.
- Open the Services tab.
- Select Hide all Microsoft services.
- Disable remaining third-party services for the test.
- Open Task Manager and disable nonessential startup apps.
- Restart Windows.
- Test Riot Client, League login, and a custom game.
- If the issue disappears, re-enable services in groups until the conflict returns.
- Restore normal startup after troubleshooting.
Hide Microsoft services first
Disabling Windows services without hiding Microsoft services can break audio, networking, login, updates, and hardware support.
9. Check Antivirus and Windows Security History
Do not permanently turn off security software as the first fix. Check whether a Riot or League file was actually blocked.
- Open Windows Security.
- Go to Virus & threat protection.
- Open Protection history.
- Look for RiotClientServices, LeagueClient, League of Legends, or Riot Games folder entries.
- Confirm that the file is from the official Riot Games installation folder.
- Add an exception only through the security app’s official interface and only for verified Riot files.
- Re-enable protection immediately after any short comparison test.
A patch can trigger a new security prompt
After a League update, file names or hashes can change. If the client stopped working right after an update, check the protection history before reinstalling.
10. Reinstall League Only When Needed
Reinstall after service status, process cleanup, Full Repair, overlays, compatibility settings, and clean boot have failed.
- Uninstall League of Legends from Installed apps.
- Exit Riot Client completely.
- Restart Windows.
- Download League from the official League of Legends download page.
- Install the game.
- Open Riot Client and run repair once after installation if needed.
- Test a custom game before ranked or normal matchmaking.
Settings issues may not require reinstall
If the problem is only hotkeys, resolution, HUD, or config not saving, use a settings-reset guide instead of wiping the whole game.
11. Collect Riot Repair Tool Logs
If the problem continues after repair, compatibility checks, clean boot, and reinstall, collect logs before contacting Riot Support.
- Exact date the problem started
- Whether it began after a patch, Windows update, driver update, or software installation
- Where it fails: login, home screen, champion select, loading screen, or in-game
- Screenshot of the black screen, loading screen, or reconnect state
- Whether Full Repair completed or failed
- League of Legends.exe compatibility and administrator setting status
- Whether Fasoo, Citrix, or other managed software is installed
- Clean boot result
- Riot Repair Tool logs
Key takeaway
For League client stuck loading or black screen, start with service status, process cleanup, restart, and Riot Client Full Repair. For reconnect loop after champion select, focus on League of Legends.exe compatibility settings, admin rights, Fasoo, Citrix, and clean boot before reinstalling.
Frequently Asked Questions
Why is the League client stuck loading after login?
Common causes include Riot service issues, a stuck client session, damaged files, overlays, graphics driver problems, or blocked Riot files. Start with service status, process cleanup, restart, and Full Repair.
How do I fix the League reconnect loop after champion select?
Check League of Legends.exe compatibility settings, clear Run as administrator, review Fasoo and Citrix conflicts, use clean boot, and collect logs when the issue remains.
Should I run Riot Client as administrator?
A one-time comparison can be useful when Riot Client will not open, but a champion-select reconnect loop often requires checking that League of Legends.exe is not forced into administrator or compatibility mode.
Is it safe to delete the Riot Games folder?
Do not delete the whole Riot Games folder first. It may affect other Riot games, settings, logs, and the Riot Client. Use Full Repair and targeted troubleshooting before reinstalling.
Why does League show Reconnect but the game window never opens?
The game executable may fail to launch because of compatibility flags, administrator settings, document-security software, remote workspace tools, overlays, or other driver-level conflicts.
Should I reinstall League immediately?
No. First check service status, close leftover processes, restart, run Full Repair, disable overlays, check reconnect-loop settings, and test clean boot. Reinstall only after those steps fail.
What if League update is stuck at 0 B/s?
That is a download or patcher problem, not the same as a client black screen or reconnect loop. Focus on storage, download, network, firewall, and patch repair instead.
What should I send to Riot Support?
Send the failure stage, screenshots, Full Repair result, clean boot result, compatibility settings, installed conflict tools, and Riot Repair Tool logs.
