This is post update.
I started matchmaking for Halo 2: Anniversary and why waiting I tried to view my last carnage report which locked the game up, locked the sound, and crashed the game. It did not crash the Xbox. I was able to go back to the home screen and it reloaded the game.
Things to note:
- The game was just updated.
- I had not been in a match since the update.
- This is repeatable
