How to fix a critical error in League of Legends

Before attempting to do anything on the game, make sure Windows and all your Drivers are updated, including the graphic card drivers. Updating your Windows and drivers to the latest version should fix any critical errors in the game.

If everything is updated and the error persists, try running the game as Administrator. Click on the League of Legends icon with the right button to see this option.

Do you still get the error? Perhaps it is an Antivirus issue. Under Search > Type Firewall and Security Protection> Open>Firewall and Network Protection. On the option to allow an app through the firewall, select League of Legends.

These three options should fix the most common causes of a critical errors in League of Legends. If none of them works, it’s time to restart the computer. Sometimes the easiest solution is to turn things off and on back again.

If restarting doesn’t work either, then it is time for the final solution and the one that should fix any error, reinstalling the game. Uninstall League of Legends from your PC and install it again — this should fix any issues.
