Hmm, I guess it must be something your computer doesn't like about the game if it also sometimes took a long time loading as well as freezing and crashing >.<
It's still strange though because, like I said, I also tested on our family laptop which is a pretty old potato laptop, and it was fine on there. I expected it not to be able to run since it can't really run most games x3 I remember trying to load Hakuoki on it and it just freezes and crashes xD So I was surprised that my games play on it at all.
I'm not a very tech savvy person, sadly >.< My best guess would be maybe your computer has low temporary memory or something, so it couldn't handle loading up the data for the next scene >.< But I don't know really :(
I don't mind sending you a dev build still though if you want me to try and get to the bottom of it :3 I've never done it before, but apparently, if I send you a dev build, when it crashes, your computer should spit out some logs with details about what caused the crash. I probably wouldn't be able to understand them myself without help, but I could post them in the naninovel support section.
Just drop me an email (melancholicmarionette@gmail.com) if you do want me to send a dev build to you, and I'll just reply to the mail with a link to it in a Google drive folder or something :3
Hopefully, it just won't crash anymore for you though if it stopped and you got past that bit x3
