Halo ce campaign freezing

For the 20k challenge I do the pillar of autumn with skulls and on legendary. Now every time I get to the end and finish the level it freezes/crashes in the score screen.

It’s funny you mention that. For the past week and a half(since last weekend’s playlist update), Halo 2 campaign missions have been crashing constantly for me. They most commonly crash at the results screen or the loading screen. But, it’s also crashed a couple times in the menu while scrolling through the missions.
