I uninstalled the game and reinstalled the game on xbox one x. It would not launch and gave me a mexican error code. After a hard reboot of the xbox one x the problems stopped and allowed me to load my game. So uninstall the game then reinstall and hard reboot for the problem to be fixed.
I am having this same problem on xbox one x. I was getting into the game about 20 hours and stepped outside of the den for quests in copper and the game froze mid save. Now I cannot load anything.
