That's unfortunate. A shame I can't think of anything else as well. The notebook I use has win10, so maybe you use another Windows, like win11 for example, and that could be it? Or your antivirus is deleting some file from your game and that is screwing with you playing, I remember that happening to me with a VN I played.unfortunately, that doesn't work either, i've reinstalled all the rtp, put the game on excluded list and play the game as administrator, still crash at certain H-Scene, funnily, the game work well on other PC(my friend pc btw), so probably the error is in the current pc i use, although i have no idea what caused it
Sorry I couldn't help mate.
