UPDATE: I believe the problem is the Vengeance of Thor ability, i have done a couple of fights without using abilities and it was fine, i used the Vengeance of Thor outside of combat and it crashed instantly.

The game crashes whenever i enter combat.. I have played around 50 hrs so far and it has only started doing it since i got to Vinland, I am unable to fight anything Guards, Bears, Wolves, Legendary Moose even Rabbits. I have tried clearing the console cache and Re-installing the game but it hasn't worked. Right now the game is pretty much unplayable.
