Xbox game bar kicking me from parties instantly and crashing the party

I would check to make sure your system is up to date as well as the game bar. There are updates on a regular basis for it and when I have had troubles in the past it was because there was an update available.

How do you check for updates?

Make sure you console is updated.

Make sure all updates are set to auto update when your Xbox is off. Double check and see if your Xbox needs an update.

Game bar doesnt need gold to be used, but either way I do have it.
