Sorry to hear you're running into that!
I'd like to get some more information from you so we can start troubleshooting.
What do you mean when you said you "quit the campaign"? Did you not play single player for quite some time?
Do you crash to dashboard after the first checkpoint in the mission Liberation, exactly?
I have been trying to finish the campaign on veteran for the past 2 weeks at first if I died during the mission Liberation I would get a message corrupt game save and would have to restart the mission from the beginning. So a couple days ago I decided to quit after the first checkpoint so I wouldn't have to watch the cut scene over and over and now when I try to restart the mission the game just crashes to the dashboard every time
Thanks for the clarification.
I believe you're on Xbox, is that correct?
Try uploading your save file to the cloud, then deleting it from your hard drive. After you've done that, redownload your save file back onto your console. Here's a very helpful article on how to do all that properly: Xbox Cloud Storage
I've seen reports about this happening to other players and it is indeed due to a corrupt file.
Thanks for getting back to me and trying that out.
Do you have a digital copy or physical copy?
You did mention that after the first checkpoint it crashes, have you tried restarting that mission over completely? I've seen other players report that the issue is resolved once they overwrite their corrupted save file.
Yeah let me know if something comes up or if you have any questions.
