Fortnite everything dark?

For half an hour Fortnite is dark with me see picture.
Games on the Xbox One S.
Can someone help me

Either it's your HDMI cable or the game. Best start the XBOX and Fortnite again completely.

If that did not work, it could also be due to EPIC Games or its server OR it's your HDMI cable. Good luck, gambler buddy! ^^

EDIT: Perhaps you have also adjusted the brightness in the settings by mistake or something else in the settings of your Xbox or the game itself?

You have to select Fortnite at the top.

On HDMI, it may not be because then probably not the map and the settings would be visible.
Believe it is the server.
