EA AntiCheat encountered an error. Please restart your PC. (9)

I keep getting this message pop up after trying to start up Battlefield 2042. It's been many months now since this problem started, it used to be (11) but now it's (9). I've done what the agent told me to do including from the website and nothing has worked, I've played Battlefield 2042 for 272.3 Hours and 25/34 Achievements from Steam. I used to play Battlefield 2042 with my brother but since this error started showing up I was never able to play with my brother again.

I need help so I can play with my brother again.
