Had crashes with the black screen constantly both with vulkan and dx 11 exe files. Then I have read here about launching the game with Shift > admin rights , it helped, but not much .Game still crashed in most cases.
occasionaly found the workaround that allows me to start the game in most cases :
1. before you launch the game have any folder open in a file explorer
2. start the game from the launcher using dx11
3. immediately after that grab the explorer window with the mouse and start dragging it randomly all over the screen
4. .... and voilà , game starts in the background.
seems that the game has got problems with initializing fullscreen on startup and needs to start with window not in focus
i run the game on win 7 with GTX 660
hope this will be of any use to smb else.
