Rust EAC "Start Service Failed" error: fix by error number

September 25, 2026
Launching Rust shows an Easy Anti-Cheat "Start Service Failed" error with a number in brackets, such as (5), (1053), (1058), (1450), (31) or (1056).
Also appears as: Error: Start Service Failed, EAC Start Service Failed, rust start service failed, rust eac start service failed, rust eac error 1053, rust eac error 1450, rust eac error 1056
Facepunch's article for this error gives a different cause and fix for each number in the brackets, all on your own PC. Numbers 5, 1053, 1058 and 1450 share a fix; 31 and 1056 have their own.
Fix it, step by step
Install the Windows hotfix (KB 2922790) for errors 5, 1053, 1058, 1450
Errors (5), (1053), (1058), (1450): install the Windows hotfix Facepunch links (Microsoft KB 2922790) and restart Windows.
If the hotfix fails, suspect antivirus flagging the EAC game
If the hotfix doesn't help on (5), (1053), (1058) or (1450), Facepunch says the likely cause is antivirus software falsely flagging the EAC-protected game as malicious. The article gives no further steps beyond that diagnosis.
Error 1056: close the game and EasyAntiCheat.exe or restart
Error (1056): an instance of an EAC-protected game is already running. Open Task Manager and close the game processes and EasyAntiCheat.exe, or restart your computer.
Error 31: kernel-mode driver cannot load, Facepunch advises reinstalling Windows
Error (31): Facepunch says the system can't load any kernel-mode driver, which points to system-level corruption. It names a rootkit or a badly uninstalled old antivirus as possible causes and says it is most often irreversible without reinstalling Windows, which it strongly recommends.
Sorted. Glad that worked.
