I’ve had this launching problem with my game for ages, EAC would block me out completely with no error message, no in log mentionings, just blank error page.
Eventually i figuered it out after literal days of reinstalls, verifications, EAC fixes, etc., turns out EAC was detecting my banking encryption app and would prevent me from launching game completely. So in order to play i would delete encryption app completely and all those separate encryption data packs, then verify integrity on steam every time just to play this damn game.
Never happened in other EAC protected games
It might be completely wrong section of the forum, or unappropriate feedback topic(sorry), but, whatever. Hope i can help at least someone.
