This appears to be a bug in Python 3.9.1. Please upgrade to a newer Python 3.9 and see if it still occurs.

Previous issue: #10300

[sochoac1]

Python upgraded to 3.12 and issue fixed. Thank you.

Issue reported also in python 3.9.0

If anyone knows how to handle the conflicts without changing python version, it would be great.

Upgrading to a newer version of Python 3.9 (e.g., 3.9.18) should be sufficient.
