Fortnite small and fuzzy?

Hey so when I try to start fortnite it always starts in such a small window and completely distorted and blurred and I can't click anything, etc. Please for quick help!

Restart the computer…

Look in the settings to see if you can increase the resolution.

Which components are in your PC?

I have a gaming pc all other games run perfectly and yesterday i also had 250 fps… So it's not because of the components but: intel core i5 frozen gtx 1660 great

As I said, I can't operate anything

It was the same yesterday… And the pc was off overnight

Update Fortnite?

Just made

Then unfortunately I can't help you either.

Can you make it bigger on the sides?

Whenever I'm in fortnite and want to press windows button, everything is first briefly black and then blurred in the top right in a small window

Press ALT + Enter when the game is open

If you can't click anything, then I recommend that you reinstall the game.

If you then open the game again, you should be able to adjust / change this in the settings.

Nice day!
