[BUG] Can't render the animation, Python3.9 not supported

[momovelo]

Description

When I try to run manim example.py BasicExample I got this output

Manim Community v0.18.0

Sorry, "python3.9" cannot be run on this version of macOS. Qt requires macOS 11.0.0 or later, you have macOS 10.15.7.

I get it, my computer is old. But meanwhile I'm perfectly able to run Manim with pyhton3.9. It seems weird that, by importing manim-slides libraries I'm not even able to render the animation.

Version

manim-slides v5.0.0
Python 3.9.9
qt 6.4.0

Platform

macOS 10.15.7

Hello, this is weird because this command should not import Qt if I read the code correctly.

What is your PySide6 version?

Also, can you try adding Qt debug symbols by specifying QT_DEBUG_PLUGINS=1 and showing the output?

[momovelo]

Hello,
Both PySide and the latest version of Qt rely on MoltenVK which requires macOS 11 or later. Therefore I can't install them.
Specifying QT_DEBUG_PLUGINS=1 doesn't seem to generate a different output.

Hum that’s sad, maybe I can make PySide6 an optional dep in future versions

See #350, work in progress.
