Whenever I press play the game starts to load, then as soon as I get the character creation camp screen my computer restarts. I've installed unreal engine through the epic games launcher to be sure it works, and I've done all windows updates and uninstalled and reinstalled the game.

I know it isn't a problem with my hardware, as I've launched it without problems before, but that was before I reformatted my hard drives.

I've also restarted my computer, although not willingly most of the time.
