The new xbox series x controller disconnects when the game is on loading on Fortnite

I believe that I would buy a new 'Fortnite' skinned controller in the new design for the Xbox Series X.

Connecting the controller with a USB cable doesn't work,

Controller still disconnects even with a USB cable connected,

I have the same issue with Series X using mouse and keyboard for Call of Duty Vanguard.

I played during the beta and there was no problems with the controller disconnecting but as soon as the game released, the controller disconnects,

I've tried a Xbox One controller Series X controller, with batteries and a USB cable, and the controllers still disconnects.

Update: ive now tried unistall/installing fortnite, disconnecting/ reconnecting my controllers, running the game through steam, and turning the controller on before loading the game, nothing has worked. This is crazy annoying

I originally just had flight simulator installed which wouldn’t load up (as if frozen) I’ve installed War thunder which does the same thing. But when I installed it on the Xbox one it worked. So I started downloading online games only on the series X none of them load up e.g Enlisted, Fortnite and war thunder. But Day Z does work.

Yea so they don’t load up at all.

It’s as if something has stopped my series X from accessing online games..

Thanks for getting back to me.

I have the exact same problem with my New Xbox series X. Tried everything include reinstall fortnite, LAN and wifi even tried it at a friend's house on another network. It just crash when it tries to enter a game
