Every time I start it, the settings change and it goes into windowed mode.

The game's display settings reset every time it starts.
When I use the L1 button in all game modes, players get stuck and don't move. My computer meets the hardware requirements. You can't afford to get early access and be so embarrassed. 

Hey EA Team,

out of curiosity - this has been an issue in EA FC 25 aswell, right?

Everytime I set my resolution to 1920x1080, the game puts me back on 2560x1440. I always get to confirm my set changes and right after I get back into the said menu the resolution is back on max. Also happens after restarts. I have to play it on lower res, since my air cooling system is louder than a airplane.

Thank you for your time, I appreciate your help.

Hey Taka12300912​ Try deleting the existing Personal settings 1 profile after launching the game, or if that's not possible, make a copy and delete the existing settings folder from this location: C:\Users[Username]\AppData\Local\EA SPORTS FC 26 (AppData is usually a hidden folder, so it can be made visible from the View dropdown.)

KingKelloggs​ See if the steps mentioned above will resolve this for you, and let me know in case of any further issues. Thanks.
