Had some frustrating issues that needed resolving due to stupid design decisions of the underlying engine, but was important to get them through. Prologue skip is a bit of a hack because why would the engine work for me when it can waste my time? Loading a simple file from a simple location, who would ever want that?
You might have to press Yes! a few times if you opt in for the prologue skip. Just keep pressing it until you get to the character renaming screen.
I presume this is just some more layers of idiocy of how RenPy handles saves behind the scenes. The loop doesn't exist, it just rolls itself back when it shits the bed until it succeeds. Usually it's 2-4 times. It makes no sense whatsoever, the loop is non-existent, looks more like an internal fail -> rollback.
Deleting your old saves (including the persistent file) might make it go on the first try. But if you're lazy like me, just keep smashing the Yes! button.
Because the developer of this engine (not me) was dropped on the head as a child, the Windows save files are located in %AppData%\RenPy\Binder-1685583850.
macOS ones are located in only a slightly more sane location, ~/Library/RenPy/Binder-1685583850. ~ is /Users/YourAccount... So, /Users/YourAccount/Library/RenPy/Binder-1685583850.
