Can't save the game after using the "back" Ren'Py feature [SOURCE OF THE ISSUE PROVIDED IN THE COMMENTS]

[Tiziano-Caruana]

What bug did you encounter?

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "renpy/common/00gamemenu.rpy", line 170, in script
    $ ui.interact()
  File "renpy/common/00gamemenu.rpy", line 170, in <module>
    $ ui.interact()
  File "renpy/common/00action_file.rpy", line 383, in __call__
    renpy.save(fn, extra_info=save_name)
TypeError: cannot pickle '_io.TextIOWrapper' object (perhaps store.requests = <module 'requests' from 'C:\\Users\\HOME\\Desktop\\LearnToCodeRPG-1.5-pc\\lib\\python3.9\\requests\\__init__.pyc'>)

This error gets dumped when I try to save the game. It doesn't trigger a crash, and we can just rollback or ignore the error, but that means that progresses will not be saved

Steps to Reproduce

Use the "back" feature at least once and try to save the game

P.S. I tried to solve the issue by myself, without success. I'll attach the save_dump.txt here: save_dump.txt

Maybe line 626 can help to identify the problem: 1 roots['store.requests'] = <module 'requests' from 'C:\\Users\\HOME\\Desktop\\LearnToCodeRPG-1.5-pc\\lib\\python3.9\\requests\\__init__.pyc'>

P.P.S. Found the problem!

The edit made to game/scripts/splashscreen.rpy in commit 458482ea93f908b7f6d6c307956881ba71f7581b is causing the crash. Performing a rollback of said edit fixes the problem, allowing the user to save the game
