when I entered the game,it dropped to 8-12 fps.

After playing the game smoothly for 10 hours in the trial version, I woke up early in the morning and my game, which was 200 fps in the menus, suddenly dropped to 8-12 fps. And it never gets better. I can't enter the match. This happens as soon as I click on the ultimate team.
Even though I deleted and reinstalled the game, nothing changed. I did a clean install, but it didn't work. My friend can play without any problems, but I haven't been able to join a match since yesterday morning because it suddenly drops to 8 FPS. What's the point of having early access? I've already wasted 2 days.
