The tutorial start.py cannot be executed properly

Describe the error

I am using the the code given as an example at https://3b1b.github.io/manim/getting_started/quickstart.html (SquareToCircle class). Those 9 lines of code are saved in G:\toto\start.py. I launch this in Anaconda prompt with python 3.12 activated. I installed ffmpeg and added to PATH, I then ran pip install manimgl. Note that the install structure is different from the one shown at this page, after running pip install manimgl I have :

manimlib/ │ ├── animation/ │ ├── ... │ ├── default_config.yml │ └── window.py ├── custom_config.yml

Also, note that running manimgl alone, I have a grey window that is not responding, and typing anything in the console does nothing.

Code and Error

The command I execute is the following, with the command output and the error following

Code: (py312) C:\Users\blabla>manimgl "G:\toto\start.py" SquareToCircle ManimGL v1.6.1 [21:09:43] INFO Using the default configuration file, which you can modify in config.py:265 c:\users\blabla\anaconda3\envs\py312\lib\site-packages\manimlib\default_config.yml INFO If you want to create a local configuration file, you can create a file named config.py:266 custom_config.yml, or run manimgl --config
