yeah there is CG there several people reported blackscreen, no idea what is cossing it, works fine for me. working theory seems to suggest it's an issue with older versions of windows, I've no idea if that panned out though.Does that scene have a cg in it?? Cause it's mainly just dialogue and a black screen, and I can't figure out if it's a bug or that the creator hasn't made the picture yet..
Maybe try his discord, that issue was reported a while back, he might have a solution by now.
