Konnte es fixen, es lag tatsächlich daran, dass ich Battlefront 2 gemodded gespielt habe. Danke an den random youtube Kommentar:
I got pass if you ever ran a mod on a frostbite game (EX. SWBF2,BF3,etc.) Then there is a variable that stays active even after deletion. Type "environment varibles" in your start menu, open the first item that comes up, click environment variables button at bottom of pop up Next Click on Game_DATA_DIR, click on the top delete button then OK. Once done restart PC and it should boot right up
