split screen campaign issues

I know multiplayer is the focus right now, however.
My wife and I play campaign split screen. Accounts Nick Phoenix and Lady Cake Ninja.
We’ve been making our way through Halo 2.
We have had several issues with starting up levels. We have had the game completely crash, 1 to 3 times per level, sometimes during movies, sometimes during play. It is always during the first couple minutes of play. If we get further into the level, it is stable.

Tonight we tried 5 times on Uprising, after the 12/3 update, and we got as far as loading, then the first energy sword on the ground, then the first brute, then loading and finally loading. We gave up tonight.

Keep working team!
