Xbox Series X Controller Randomly Disconnecting

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.

Alright. Please keep this in case you need it Press the Xbox button to open the guide.

Select Settings > System > Console info > reset then keep my games and apps.

It's worth a shot though but to best isolate the issue, have you tried any other controller? I asked because if it happens to other controller, I'm afraid the console needs a service.

Hi! My name is Pam. I'm an Independent Advisor and I'll be glad to help you today.

Do you have an external hard drive plugged in to the console right now? Or any other wireless devices that is attached or near your console?

I see. This time, I'll be providing you a step to restore your console to its factory defaults to remove all potentially corrupted files that can interrupt you from using the console’s full potential. Nothing to worry as everything will stay intact, you just need to sign in using your account. No games or apps will be deleted. Make sure you know your emails and password, okay?
