Game freezing upon start of CE missions

So even though I was perfectly able to start and play The Silent Cartographer the other day to get the Pacifist achievement, when I was finished and I went to start up Two Betrayals to get some achievements for that mission, it freezed after starting the mission before the loading screen even pops up. I’ve restarted the console. Same thing happens. I’ve left it alone for awhile and came back. Still freezing. I’ve had this problem before with other CE missions though I don’t specifically know which ones. I guess some others are experiencing this problem too. Seems like 343 would want to get on this. I’m enrolled in the insider program but I’m playing my regular MCC, not the Insider Program version.
