League of Legends won't start after champion select
Security software or old settings block the game
Champion select ends but the loading screen never starts. Riot points to background programs, security software, old graphics drivers, compatibility mode or damaged files.
How to fix it
Do a clean boot to rule out background programs.
Add the League, Riot Client and Riot Vanguard files as exceptions in your antivirus or firewall.
Update your graphics card driver.
Turn off compatibility mode in the properties of the game's .exe file.
Repair the game in the Riot Client settings, and reinstall it if that fails.
