Did you install manimgl directly by pip install manimgl? I dont have a same problem, but when I enter the interactive command line, I cannot type a "(" as it will raise the same error as yours. The problem solved after I reinstall from the master branch.

This issue seems to not be related to manim, but IPython. For some reason the shell in return shell.auto_match in the file IPython/terminal/shortcuts/filters.py is a NoneType, which I assume is a bug in IPython, try reporting this to IPython instead.

Thank you for your suggestion, I'll try it later .> Did you install manimgl directly by pip install manimgl?

I tried the method you mentioned, but it's not work for me. Thank you.

So could you tell me if there are any solutions now? I tried some methods, but none of them worked.
