Same here; on Xbox and had the error, though only on the first time I attempted to load my last save. After that first time, the game seems to load properly until the screen goes black and I’m returned to Xbox home after a short while.
I found some old posts from last year, when the same thing seemed to have happened to several reporting users. They where able to fix it then so I hope they can do it again.
