So I'm not entirely sure that this was because of your game, but I think there's a good chance. I think it caused my video driver to crash. I can't be sure because my computer seems not to have logged it, but it froze up mid sentence and then the entire screen went black before starting back up again. The game is still a black screen but otherwise my computer is working fine again.
I was playing Dimitri's route, Chapter 2. MC had just got ditched by Alex and they were sitting on the sofa talking about Dimitri's birthday. MC was in the middle of the line where she wonders if she did something wrong.
I just replayed the scene without issue. If it happens again I will update.
I'm sorry, I wish I had more info or was more certain, but it was alarming enough that I at least wanted to give you a maybe report.
