[2021] [Peripherals]Im having trouble with ingame accesibilities about my PC

The problem is that i play on PC i bought the gave like 4 years ago, haven't played it in a while and downloaded it again, so i get to the main menu and every key on my keyboard working fine and having no issues, while i join the game operator select working fine i can press esc, space to view loadouts etc. But when i actually get into the game i can no longer do anything with my keyboard inside the game except alt+f4. Because it has registrated an xbox controller somehow, i dont even own an xbox controller i cannot change it to keyboard priority in the settings, please help, thank you very much.
