Check the process
- Open Task Manager with Ctrl + Shift + Esc. Look for ARC Raiders in the running applications or processes.
- End only the clearly identified stuck game process, then launch once through your launcher.
02
Restart Windows
- If no process is visible, save your work and choose Windows → Restart.
- Try launching once afterwards and note whether the same message returns.
03
Separate other errors
- A different EAC code after reboot is a new diagnostic result. Record its complete text.
- If the instance error immediately returns, send the launch sequence and screenshot to Embark support. Do not delete EAC drivers speculatively.
