Open cmd so z. B. At Win-Key enter + R and then cmd and enter "sfc / scannow" in this window. Then cmd will scan for errors in Windows files.

If nothing changes then upload crash logs here or update the graphics driver.

Thanks I try that with cmd and the graphics driver is already up to date

Do you close the Epic Games Launcher while playing Fortnite? If you close it, leave it open.
