Thank you for reporting. Unfortunately it's unlikely I will find time to do something about this in my lifetime because I'm not that great at coding.
The workaround ( https://itch.io/post/9825970 ) seems to not be much of a help.
Similarly to < https://itch.io/post/9654438 > the loader.py file has been tuned to do some binary shidangle. If you use for example kdiff3 to compare it to the same file in the RenPy SDK 8.30, you will see the differences. A better programmer might be able to figure out how to untangle this hexamishmash.
