Won’t start and device-block troubleshooting
Direct answer
For a device-block or ban message, use official support; reinstalling or attempting to bypass anti-cheat is not a valid appeal. For an ordinary launch failure, verify files, drivers and system requirements first.
Officially confirmed
- The launch FAQ warns that cheating on a Family Sharing account can affect borrower and lender.
- Community users have reported device-block messages before entering a match.
- Only official support can review an account or device enforcement decision.
Why players search this
- “Game won’t start,” “fatal error,” and “device blocked” appear in Steam discussions.
- These symptoms have different causes and should not share one speculative fix.
What to do now
- Screenshot the exact code and record account, time and region.
- Verify Steam files and remove conflicting overlays for ordinary crashes.
- Submit the enforcement case through official support without evasion attempts.
