SOLUTION FOUND?? Latest Update:
- so, one thing I saw online and tried, was going into my steam files and finding EAAntiCheat, running anticheat as an administrator (which launches the game, at least for PC Steam), and so far it has worked flawlessly. Knock on wood.
- not sure if this is a permanent solution but worth trying as it seemingly has worked for me.
- Open up file explorer, go into Local Disk, then Program Files (x86) > Steam > steamapps > common > Battlefield 6 > find EAAntiCheat.GameServiceLauncher (blue EA Icon), and run this as the administrator.
