Help Halo 2 A Problems

Hey so I have been unable to play Halo 2 A for the past few days. It will only let me play my resume game any attempt to start a different mission results in a crash no matter the mission. Anyone else go through this recently? Just looking for any help here. Haven’t seen any bugs like this in ages.

Thanks in advance.
