FC 26 FPS DROP ISSUE

After 1-2 matches, I suddenly experience an FPS drop (FPS VALUES: 2-15 ). This can sometimes happen in the first match too. I've tried everything to fix this, and I'm really tired of it. I've been dealing with this issue since I bought the game. Here's what I've done:

1- I uninstalled and reinstalled the game
2- Installed multiple GPU drivers (old and new) (with DDU)
3- Verified the game files
4- Set the graphics settings to the lowest in the in-game settings
5- Toggled Vsync on/off
6- In Nvidia GPU settings:
(High Performance, Vertical Sync: On, Low Latency Mode: On)

7- Windows settings > hardware GPU scheduling: on/off
8- In-game settings: set the game to 4:3, windowless, and full screen
9- Deleted the game's cache files

I've been struggling to find a permanent solution, just to be able to play for 5 minutes. Also, When I downgrade the GPU driver version, the game crashes because the driver is outdated. This game has caused me both financial and emotional damage. Is there anyone who can help me with this??
