Played on particular community server 300hrs+
Ryzen 5600x+MSI B550 Torpedo 1.2.0.3c bios
Updated to Windows 11(you know TPM 2.0 enabled required for system install)
Joining same server -
> BE connection with remote machine could not be established. Error=3

> Warning Message: BattlEye initialization failed
Tried playing on Vanilla official Warlords and Vanilla Koth, no issues
Solution: Go to bios - Trusted computing - turn off TPM key
