(I know I reply 2 months later, mainly because I have a kinda bad internet connection, in fact I live in the country with the WORST internet, that is the reason)
I was searching a bit about the Not implemented thing, it is about the audio, I can install the game and even run it, the bug occurs when I start a New Game, specifically in the part which says “You aproach the building...“ then it crashes, other details are, the PC with the error thing runs Windows 7, while my PC, which does not have it, runs Windows 10, I think it is because there could be a damaged audio lybrary or DLL required that Windows 7 may not have, or maybe, the audio that is supossed to play there is damaged.
Here is a screenshot
