Halo 2 consistently crashing

Hi all.

Ever since mid-day yesterday I’ve been unable to play Halo 2’s campaign, it was working fine in the day and after unlocking the achievement related to the 8? Halo 2 toys, my game has been crashing on most levels, I’ve tried setting the graphics/ost to classic/anniversary and it still crashes. I’ve only been able to load it upon going onto Normal difficulty, any time the difficulty is increased/lowered it’ll crash, if a skull is added even on normal it also crashes. I’ve reinstalled Halo 2’s campaign 8 times, and hard-booted my console multiple times in order to fix it. Earlier this evening, I decided to just fully uninstall the MCC (I have both a physical and digital version thanks to GamesPass) and both crash. I don’t know what else to do.

If you have it installed on an external drive, have to you tried installing it on the Xbox’s internal drive? Sometimes certain games don’t play nice with certain external drives.

It’s on my internal drive, yes. I don’t feel like moving it over to external to test that, I’ve reinstalled MCC way too many times in the past day or two now, it’s been fine for years, and now out of the blue its just decided. “Nah I ain’t gonna let you play Halo 2.” Earlier on in the day, I believe it was Saturday? It was working just fine, it was only after I had unlocked the achievement for collecting 8 Halo Toys that it started to constantly crash loading campaign missions for H2. Ever since then, I’ve not been able to play it, after multiple re-installs both MCC as a whole and Halo 2’s campaign with the management. Just a few hours ago I attempted clearing my local saves and clearing the system-cache and that didn’t do anything either.

I found a post with a similar issue on Reddit and on the Waypoint forums, both dating around Jan/Feb time, seems to be a bug that was ‘added’ around the January update.
