A game that closes at launch without restarting Windows is different from a system stop error. Check which layer failed first.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
What to record
Game message, Event Viewer application entry, GPU driver, and whether other games start.
The exact message, Windows version, and whether the desktop still opens matter more than a guess based on the symptom name.
Try these safer checks
Verify game files through its official platform, then compare PC and graphics drivers with vendor support.
Change one thing at a time. After each check, see whether the same symptom returns and write down what changed.
When to stop and get help
Avoid third-party driver bundles or security-disable steps.
If this is a work or school device, contact its administrator before changing managed settings.
Keep track of your checks
