Games crash?

As of today, the games start short and crash directly. What can I do?

in advance = I don't care if someone has minecraft fortnite what ever

Which game has crashed and other games crash too?

Minecraft doesn't crash, only fortnite…

Then why do you say "the games"?

I thought it was all games = D I made a mistake

Then restart your PC once, if it doesn't work you have to reinstall Fortnite.

Would reinstall the game.
