End 3rd Party Applications from Running

Open up your Task Manager by searching for it in your start menu search. If the Service Control Manager tweak did not help, the error is caused by 3rd party software running in the background. In your Processes tab, end all processes showing an overlay while playing the game (Steam, Skype, Discord, GeForce Experience, etc.).

Next, go to "Program Files" and "Riot Vanguard." Select the option to uninstall Vanguard from your system. After uninstalling Vanguard, make sure to restart your PC. Once your PC has restarted, open the Riot Client. The client will automatically download and reinstall Vanguard to your system.
