Hi, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

To fix this, please perform a power cycle on your console by following the steps below:

POWERCYCLE CONSOLE​​​

1. Turn off your console by holding the Xbox button on the front of the console for approximately 10 seconds. The console will turn off. ​​​

2. Turn your console back on by pressing the Xbox button on the console or the Xbox button on your controller. ​​​

If that didn't work resetting the console keeping games and apps will be the next option. Don't worry because as long as you're connected to Xbox Live your saved progress, games, will not be deleted. It will remove all of your accounts but you can add all of them later on.
