I also downloaded from kemono via the download link on pCloud and also came across this blue screen. By and large, it was my fault, as I did not suspect anything suspicious about the fact that the archive was without a password, since everything inside corresponded to the original (I kept a later version for a long time) and the game itself worked as usual for the first 10 minutes, but in general, I changed passwords everywhere and it seemed nothing happened, so I'm inclined to believe that this is just the banter of the developer on those who downloaded the game from kemono
