Halo 2 missions not playable

Halo 2 missions on MCC PC won’t work. I’ll select a mission it’ll show the loading bar filling up then it’ll just stay at the loading screen while the music still plays. At that point you can’t even exit out of that window whether its by windows+tab to the steam window and clicking “stop” or just by right clicking the MCC icon on the task bar and clicking exit out. Instead I have to click start and restart the PC. I’ve Uninstalled and reinstalled Halo 2’s campaign 3 times, and I’ve Uninstalled the entire game and reinstalled it, didn’t help. I’ve checked the integrity of the files, wasn’t missing any files. Didn’t help. But the Halo 2A and Classic Multiplayer work just fine. Anyone having this issue? If so can you tell me how you fixed it. Thanks

I would contact support about that.
