Severe FPS Drops (5-10 FPS) in every game mode, even in Menus

It's been five weeks now that I haven't been able to play FIFA 26 because every time I join a match, my FPS drops to 5-10 and it costs 100% of my GPU. It's completely unplayable, and I've tried everything to fix it, but nothing seems to work. I just want to enjoy the game again, but this issue makes it impossible to even start a match.
