So, update: seems like any ren'py game with a launcher will crash on launch for me, but only after the launcher has finished loading. i managed to make it work last time by running a disk check on the drive it's on....which took like an hour and a half.
it's not the game itself clearly, but something wrong with either ren'py or my system, and ive no idea which. @_@
2nd update: now it's suddenly happening on multiple drives......I legit have no idea wtf is going on.
Attaching log file, though it seems to have nothing important, maybe im wrong.
