Managed to fix it, scroll down.
Any ideas anyone?
I’m getting this error today when launching Rust, … I haven’t done anything except turn my PC on and I was playing Rust fine yesterday. I think this is an EAC problem as i can launch RustClient.exe OK !
-Delete EAC service & Reinstall
-Run as admin / Remove run as admin
-Verify Integrity Cache
-Disable Windows firewall & AV
Nothing is working,
