Fortnite crashes when I go to fullscreen what do I do?

I used to play streched on my pc but I don't want that anymore so I made all the settings as before in '' GameUserSettings '' but now my game crashes when I go to fullscreen. I have updated my driver from miener graphic card.

CPU: AMD Ryzen 5 3600

GPU: Geforce RTX 2070 Super

Motherboard: Asrock B450M pro

(if you can do anything with it?)

It's best to leave it at the status quo.

Reinstall the game, that could help - otherwise I suspect the graphics driver, I've seen that a little more often.

Maybe it has something to do because I changed the game user settings?

Also possible… Phew, play Apex instead.

I played but I don't really enjoy grade so much.
