Quick Note Before You Start

Before diving into troubleshooting, make sure you have the following done:

  • Stable Internet Connection: League of Legends requires a reliable internet connection to work properly.
  • Check for Windows Updates: Sometimes, missing Windows updates can cause compatibility problems.
  • Close Background Programs: Programs running in the background may interfere with the game’s performance.
  • Save Your Progress: Although League of Legends progress is saved on Riot servers, be sure to note any settings you might want to restore later.

Step 1: Run League of Legends as Administrator

Running the game with administrator rights can solve permission-related issues that prevent the game from running correctly.

  1. Right-click the League of Legends shortcut or executable file.
  2. Select Properties from the menu.
  3. Go to the Compatibility tab.
  4. Check the box that says Run this program as an administrator.
  5. Click Apply, then OK.
  6. Launch the game and see if the issue persists.

Why this helps: Administrator mode allows the game to access all necessary system files and resources it needs to run properly.

Step 2: Update Your Graphics Drivers

Outdated or incompatible graphics drivers often cause bugs or crashes in games, including League of Legends.

  1. Press Windows + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for drivers and follow prompts.
  5. Restart your computer after the update completes.

Alternative: Visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download the latest driver manually if automatic update doesn’t work.

Step 3: Repair League of Legends Client

The Riot Games client has a built-in repair tool that can fix corrupted or missing files causing bugs.

  1. Open the League of Legends launcher.
  2. Click on the Settings icon (gear symbol) in the top-right corner.
  3. Select Initiate Full Repair or Repair option.
  4. Wait for the process to complete; it may take several minutes.
  5. Restart the game after repair is finished.

Why this is important: Game files can get damaged during updates or installations, and repairing ensures all files are intact and up to date.

Step 4: Disable Fullscreen Optimizations

Windows 11’s fullscreen optimizations sometimes conflict with games, causing stuttering or crashes.

  1. Right-click the League of Legends executable file.
  2. Select Properties and go to the Compatibility tab.
  3. Check Disable fullscreen optimizations.
  4. Click Apply and OK.
  5. Try launching the game again.

Note: This will disable a Windows feature that aims to improve fullscreen performance but can cause issues with some games.

Step 5: Adjust Windows Security Settings

Sometimes, Windows Defender or other antivirus software can block League of Legends files, causing bugs or crashes.

  1. Open Windows Security from the Start menu.
  2. Go to Virus & threat protection.
  3. Click on Manage settings under Virus & threat protection settings.
  4. Scroll down and click Add or remove exclusions.
  5. Add the League of Legends installation folder as an exclusion.
  6. Restart your PC and try running the game.

Why do this: Antivirus software can mistakenly flag game files as threats, blocking them and causing errors.

Step 6: Reinstall League of Legends

If none of the above steps work, a clean reinstall may fix persistent bugs.

  1. Press Windows + I to open Settings.
  2. Navigate to Apps & features.
  3. Find League of Legends in the list and click Uninstall.
  4. After uninstalling, restart your computer.
  5. Download the latest installer from the official Riot Games website.
  6. Run the installer and follow the on-screen instructions.

Important: A fresh install replaces all files and can clear corrupted data causing bugs.
