Could you try playing the game in a web browser (https://pulsus.cc/play) and tell me if you get similar results? The screen may not turn grey, just wondering if it will still crash consistently.
Absolutely, no problem at all. I'll poke around at some things. I have tried the simple things like, administrator on/off, anti-virus exceptions/on/off entirely and the like. No change there.
If theres any information I have that could be useful for you just let me know, specs or what have you. Not sure if anything there would be of use.
