I recently started experiencing this.
I'm interested in figuring out what actually causes this, and solutions that don't include physically moving hardware around or disabling devices.
In my specific case, I see a black screen for 20-30 seconds. If I *don't touch anything*, the game will eventually start. If, after starting the game, I interact with any other window, the game window will freeze. or otherwise fail to render anything but white.
Others who have this issue- could you simply not touch the computer, and wait for a minute, to see if the game does eventually start? I want to make sure this is the same bug.
