The Game Crashes. All the time

I’m playing on Xbox and in since i installed the november update and the DLC Alpine Unrest the game has crashed ten times. Ten!..
Is anyone else experiencing this issue? And why does the game crash. A couple of times it crashed when i was just running around och looting, and other times in the middle of a combat.
It’s a horrible experience, although i do want to like the dlc and update…
