1. Update Display Drivers

Outdated or corrupted drivers can prevent League of Legends from running properly. Checking for driver updates is an important step to resolving this issue. We recommend using Driver Talent to automatically detect and update drivers, saving time and avoiding the risk of downloading or installing incorrect drivers.

Download Driver Talent

Click the download button to get the latest version of Driver Talent, then open the software and click "Scan".
After the scan is complete, it will display any missing or outdated drivers. Find the display driver in the list and click the "Download" button.

2. Disable Steam In-Game Overlay

Open the Steam client and log into your account.

Click the Steam icon in the top left corner, and select "Settings".

In the window that appears, click the "In-Game" tab on the left side, and uncheck the option "Enable the Steam Overlay while in-game".

5. Disable Antivirus Software and Firewall

Disable antivirus software:

Open your antivirus software and pause or disable the real-time protection feature.

After disabling the antivirus, try launching League of Legends again.

Turn off Windows Firewall:

Press Windows + I to open "Settings".

Click "Update & Security" > "Windows Security" > "Firewall & Network Protection".

After disabling protection, try launching the game.

Note: If the issue is resolved, it's recommended to add the League of Legends installation directory to the antivirus software's trusted list, so you don't need to keep the protection disabled permanently.

6. Reinstall the Game

Press Windows + R, type "appwiz.cpl", and press Enter.

In the program list, find League of Legends, right-click and select "Uninstall".

Open the game's installation directory and delete all related files and folders.

After uninstalling, restart your computer.

Visit the official League of Legends website, download the latest version of the installer, and follow the instructions to reinstall the game.
