Fatal Error when loading Single Player Game

I have played 140+ hours no issue, even after lastest release I was able to play and no problem. I use one mod which enables levelling beyond 60. Starting last week I can no longer load my game. I access through Steam, hit continue and the game almost completes loading and then fails right at the end with a fatal error and no other relevant information. I would gladly post a log if I was able.

Kind of dumb I can’t upload the log file because I am new user. I am pretty sure you can’t resolve without at least seeing the log???
