I have had the same problem for almost a year now and nothing I found on forums or on the internet in general has worked so far. No official response either. I'm mainly playing on a laptop which is what I keep having the issue on and the only way I can even start the game is by disabling my Nvidia card and running the game on the integrated card, which is not very optimal since I give up 40-50 fps that way and I'm forced to play with 15 fps max instead of 60.
