PC FPS DROP

I bought FC26 when its released. I played soo many times without trouble. But i have an big issue right now. When i want to play -doesnt matter which mode it is its happening on every modes clubs, ut, kick off, my career mode- my suddenly drops from 200 to 10-11 . I tried everything to fix it. I think its like a vram leak or something like that. Please fix this bug. This game is unplayable right now.
