Hello Jacob, I don't know what your console model would be, but try to follow the procedures below.

Xbox One reset keeping Games:

Press the Xbox button to open the panel.

Select system > Settings > System > Console Information

Select Reset console.

Restore and maintain my games and apps.

Rest assured, you won't miss games or saves

Note: You need to know the email and passwords of your accounts when performing this reset.

Also when i first connect the headset to my xbox and start a party to test it, the circle around my picture flickers up for a split second and my name on the overlay does the same, then nothing after that.

When Im connected via remote play, I notice no one can hear me in games like Sea of Thieves, but I hear them, I have my headset connected via my pc. The icon on the top right says I have a mic connected but when I go to edit the settings in party chat to see whats wrong, everything is greyed out and I can't turn it on, edit the volume, etc. Also my headset model, idk what it is but it works everywhere else on my pc
