Your Fireteam has changed bug

My game has recently started coming up with the error, your Fireteam has changed and then it returns me back to either the main menu or arena lobby. It keeps kicking me out of games when it does it. Even when i’ve just turned the game on and am waiting in a lobby on my own it will say Fireteam has changed and take me back to the main menu. The game is currently unplayable for me. plzz help

Quit out of Halo 5: Guardians and hard reset your Xbox One, wait 30 seconds then do in reverse. This should reset Halo 5: Guardians to it’s initial launching code (as if a disc was inserted) and clear your Xbox data cache for possible recurring bugs. Hope this helps.
