I checked the things you mentioned, and tried to run the game after that, but I have got the same issue as I had in March. (I can play the game when I open it from the folder though).
So I launch the game, and the window pops up where I should select if I want to play single- or multiplayer. I started the single player version. The picture with the snowy background loads correctly, after that the smithing animation is played. When the animation ends, and the other loading screen comes, the game always crashes.
And I want to add an other thing, I hope it helps to find this problem: Last year I got an invitation for the Beta version. I played a few hours with it, but at the end of last year I had similar issues like I have now. When I can find the time I am going to reinstall my Win10, and download the game again.
