FiveM ExitCode 500 after update restart – Epic Games GTA V

FiveM Client Support

What is the issue you’re having?

FiveM fails with “500. Failure connecting to the Rockstar Games Launcher! (ExitCode = 500)” after FiveM asks to restart for an update or game-data update.

GTA V is owned through Epic Games. GTA V launches normally through Epic Games and reaches the main menu. The Rockstar Games Launcher also opens and I can sign in, but FiveM fails after its restart before I can join a server.

What have you tried already to fix the issue?

  • Restarted the PC
  • Reinstalled FiveM
  • Reinstalled the Rockstar Games Launcher
  • Confirmed the Rockstar Games Library Service is running
  • Started GTA V normally through Epic Games; it works
  • Cleared FiveM Rockstar cache: %LocalAppData%\DigitalEntitlements and %AppData%\CitizenFX\ros_id.dat
  • Checked the GTA V folder; no dinput8.dll / ScriptHookV file is present
  • Ran both FiveM and Rockstar Games Launcher without Administrator mode

The issue is reproducible specifically after a FiveM update/restart.

What server did you get this issue on?

No specific server – the error happens before joining a server.

Windows version

Windows 11 (exact build unknown)

System specifications

System specifications available on request.

Antivirus software

Windows Security / Microsoft Defender (no third-party antivirus mentioned).

Additional comments

A CitizenFX crash dump is available and can be attached if needed.
