No module named 'renpy.display.scenelists'

[mold.FF]

Hello,

When attempting to launch the project on Mac through Steam, an error occurs. It doesn't happen immediately, but after the splash screen. On Windows, the project launches and functions normally.

I want to clarify that instead of the main menu, I'm using the following construction:

Code: Select all

label main_menu:
    if persistent.story_progress is not None:
        if persistent.unlog_label is None:
            $ FileLoad (1, confirm = False, page = "auto", newest = True)()
        else:
            $ Start("re_log")()
    $ Start()()
label re_log:
    $ act2_loop_visited = persistent.unlog_visited
    $ lbl = persistent.unlog_label
    $ persistent.unlog_visited = None
    $ persistent.unlog_label = None
    
    jump expression lbl

The idea is that the player plays without saves, and in some cases, they have the option to "exit the game" - in this case, upon the next launch, the game will start from a special label.

How can I fix this?

I'm sorry, but an uncaught exception occurred.

While running game code:

It looks like you're loading a save made in a newer version of Ren'Py into an older version of Ren'Py. That's not supported.

The idea is that the player plays without saves, and in some cases, they have the option to "exit the game" - in this case, upon the next launch, the game will start from a special label.

Would a persistent variable and the before_main_menu label work for you?

Update: turns out the issue occurs only on one single machine, no issues on others.

I don't see how this scenario is possible - game is a month old, and user received a built distributive, with no saves beforehand.

So I consider this issue as "just bad luck dude, something wrong with your mac".

Thanks for the advice, I would try to use before_main_menu if issue wasn't solved.
