Oh dear. I'll see what I can do about that. My husband and I are currently remaking it in unity, instead of the visual novel maker engine that I use currently. Hopefully that'll fix the issue if I cant fix it for you now. Though I should mention it does take a little time to load the next scene sometimes.
-edit- I cant seem to get it to crash at the window opening... I even downloaded the version I have up. But I'll let you know when when I re-upload it with unity as the engine instead. NVM can be kind of buggy ;; which is why we're redoing it in unity ;;
