krutai7 unfortunately EA doesn't post any information about what these anti-cheat error codes mean.
I would start by uninstalling and reinstalling EA anti-cheat.
- Navigated to: C:\Program Files\EA\AC\EAAntiCheat.Installer.exe
- Right clicked, ran as administrator.
- Selected "Uninstall All"
- Closed the Program
- Restarted the PC
- The directory C:\Program Files\EA\AC automatically deleted itself after the restart.
- I downloaded EA AntiCheat
- I right clicked the .exe, ran as administrator. Installed the BF6 Files.
- I uninstalled the "EA App"
- I downloaded the EA App
- Installed the EA app in administrator mode. Logged in. Double Clicked BF6, "This app needs permissions" popped up, clicked OK.
- The Splash Screen stayed up for a very long time. It prompted me to login a second time, but this was new!
- THE GAME LAUNCHED.
- I closed the game, made sure it launched with Steam, IT DID. Problem SOLVED. Other than the fact it takes like 5 minutes to load the main menu.
The lesson here: Listen very carefully to each step in Solution Eight. Skipping anything in there will result in a failure, restarting is essential, admin mode essential, etc.
If that doesn't fix the error then I don't know what's causing it. There could be multiple reasons. The anti-cheat might not like a driver or software app installed on the computer. Make sure no other anti-cheat software, like Riot Vanguard, is running in the background, as they can conflict with each other.
Perhaps there's a connection issue to the anti-cheat server. You can try connecting to Cloudflare Warp VPN and see if maybe that fixes a connection issue to EA anti-cheat server.

Unfortunately the fastest way to diagnose issues like this is to do a fresh install of Windows on a spare hard drive or USB stick and see if that fixes the issue.
The only people who know what those error codes mean is EA's anti-cheat team, and they're not saying anything.
