PBE crashes at 90% on Loading Screen

Whenever i start a game (I tried every mode) on PBE, i can pick the Champion, wait to go the loading screen, but when it hit 90% of loading the game crashes, saying "League of Legends.exe has stopped working". I tried to create a DMP file from the League.exe but it was blank so i couldn't click it, does anyone knows how to fix it? {{sticker:sg-ahri-1}}
