fixed the issue, has to do with Nvdia performance counters which probably this version of renpy requires full access tofor some reason can't even start this version of the game.. CH3 was fine but trying to load CH4, a black screen pops up, then monitor flashes black and window disappears. This happens with or without mods. Other games running on renpy are working just fine. On Windows 10 and I've tried redownloading a few times, same behavior each time.
Anyone else running into this or have any suggestions?
