From what I see the issue is related to one of the libraries used by manim and not in manim itself. Try reporting this to IPython.

I had the same issue. There is no problem with your manim version and your python version. The problem is with the IPython version. You need to install this version of IPython:

pip install IPython==8.0.1

same issue. maybe there's some changes in the latest version of ipython leading to this problem. Manimgl should be adapted to the new version or add "ipython == 8.0.1" in the requirements.txt.
