@vadoobs As far as I'm aware, repairing the game is only a thing you can do on PC through Origin, it's not applicable to Xbox/consoles. Sorry about that 🙂
This, unfortunately, is a problem I've seen a few people have (though usually on PC), and I'm not sure I've come across a definitive solution for it. I'm pretty sure it's not a network/internet error (as you're playing in single player mode, and that is not what happens when your internet drops out while you're playing, unless it's different on console), it just appears to be due to the error message. However, just to check, have you tried playing while not connected to the internet, see if that makes any difference? Really, all that should happen is you lose the ability to cloud save or upload progress to the Keep, as long as your DLC is authenticated (if you have any).
I'm a computer person, don't really know anything about consoles, so I'm afraid I can't really be more help, I'm sorry. Hopefully someone else can be.
