Slow motion gameplay

I bought this game in December on my laptop. Since then, every time I play it, it runs in slow motion. I mostly play Career Mode and Kick Off. For the first few seconds, it seems fine, but after that, the FPS drops and the game goes into slow motion.

All the settings are on low. Stadium and player shadows are turned off, and even the menu videos are disabled. I have tried everything, but nothing works. I have played FC 25 and FC 24 on the same device, and both games run fine, but FC 26 doesn’t.
