Banned after game crashed mid game

Hello. In a casual game of Halo CE multiplayer, my game had a fatal error and crashed. When I got back on, I was banned from the game for 24 hrs. I know 24 hrs isn’t too long and I can wait, I’m just curious what happened here. Thanks!

Hey OP, please use the ban thread pinned at the top of the MCC Xbox forums for any queries on matchmaking bans
