Xbox Version Crashing

[Underceej21]

I’m stuck on the following area and when exiting my ship to enter cloister overlands my game crashes and goes to Xbox menu.  Happens every time now and even switching to alternate quests it shuts down when I travel. 
 

if helpful I had attacked all personnel in cloister and am attempting to progress into a sealed area for advancing the plot but no attackers left and was somewhat stuck at this point in the game.

How do I proceed? I loaded an older save and it still shut the game down when I fast travel.
