This has been an ongoing issue for years, with many posts from various players. The speculated solution regards account-syncing, but this requires messing with one’s account which is dangerous.
Checked the issue today on xbox one after “Raven” update dropped, and selecting any Spartan Ops mission still immediately crashes the game. So far this has never even been addressed in any patch or update. At this point it seems unlikely anyone from 343 will attempt to fix it. Which is a shame, as Spartan Ops is underrated and quite enjoyable.
Just thought I’d shout into the void once more. Any help would be appreciated.
