Try a hard reset if the Xbox. This is usually my first step if I run I to any problems. With the Xbox on hold your finger over the lit Xbox symbol on the front of the Xbox till the light turns off ( 3-5 seconds ). Unplug the Xbox from the power supply and let it sit for 2-5 minutes. Replug it in and if it hasn’t already done it turn it back on. It will take much longer yo get to the normal main screen but when it gets there sign in if it has not recognized you and hopefully you are good to go. If this doesn’t work post it here and perhaps someone else knows more than I do and will help out. I also will be watching as I may learn something also.
