I was thinking it was probably a mod conflict issue so I tried a new run with just the offical content & it happened again during a stripping action at a student home.
So I guess it's just that this software & my hardware are really angry at each other for some reason; weird.
Let me make a wild guess here.. You have Nvidia graphic card and using the latest drivers?
I've been having issues with all my Ren'Py games closing down for no reason, with no reports, as well, for a month or so.
Investigated and tried to fix it for a while, had tech friend help, long story short: It's an Nvidia driver problem, probably connected to i9 processor and windows update.
Shift+G when game started will allow to chose a different Renderer option, upper left corner, it's set at Auto as default, change that, Quit, start game again.. see how long it last, if not, try the other Renderer option.
This made it possible for me to play for longer, but it still crashed at some point, after a few hours, so I endured it.
Then Nvida had a new driver update, Arpil 16, which made even that work around pointless, could not play 5 min before it crashed.
Investigated more, turns out Nvidia drivers been causing problems for months because they focus on the new cards (5k series) and doesn't included the older cards like they used to, so unless you have a 5k card the driver update would cause issues with some games.

I downloaded the latest reported stable Nvidia driver, from Dec. 5 I think it was.. did a clean install, but still have crash issues on random play times, but at least I can play for more than 5 min, just remember to save often
Am still trying to figure out why it keeps happening, it's a software and hardware thing for sure, maybe in my case some driver file was not removed completely when clean installing the old ones.
Have no overclocking, no overheating, BIOS updated to latest version, everything updated as it should. Other game types work as they should, it's only Ren'Py games, for me, that keeps crashing at random.
High profile competetive gamers have reported black screen and various issues for months with Nvidia driver updates, if they use a 3k or 4k series card, using RTX 4080 myself, heck even 5K gamers report issues in some cases...
If you don't use an Nvidia graphic card, then it might still be a driver issue.. could be windows related?
