Can't Join Big Team Battle Without Crashing Game

As the topic says, I cannot join big team battles without having my game crash as soon as the search bar finishes. I will get a full lobby of players by the time. I’ve tried to troubleshoot with Microsoft support which didn’t help. This also happens sometimes for any game mode other than quick play. Please help, I’ve been with the halo franchise since the first game, please don’t let my love affair with the game end here.
