Gymnasium: [Question] Weird TypeError occurs when trying to import gymnasium

Question

I am trying to use the latest version of gymnasium with python 3.10.6 on Ubuntu 22.04. When I type import gymnasium, I get the following error:

Traceback (most recent call last):
  File "/usr/lib/python3.10/idlelib/run.py", line 578, in runcode

    return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or bytes-like object

I would greatly appreciate guidance on how to fix it.
