This is most likely due to the fact you have a copy of an older build on your computer. For some reason, this always messes with RenPy created games for me--most likely due to the changes in the script that creates this error as you are trying to load a game with certain aspects that no longer exist if that makes sense. To fix this, permanently delete the first build. Not by putting it in the trashcan, but by going into your App Data on your computer. To do this, press the Windows + R key at the same time, and copy this:  %appdata% and click enter. Then, find the application for the old build, and delete everything. Sorry if I'm bad at explaining, there are many tutorials online--I'd put a link but then my comment with get flagged! I hope this helps girl <3 LMK if you still have this issue, but for me this has fixed it every time :)
