When trying to run mock to test RPM builds I python errors but not sure where the issues are coming from. I am installing mock from the RPM repos.

mock --help

Did you install any packages from PyPi with pip as root?
Do you have PYTHONPATH set?

Im sure I have installed packages as root but i don’t believe PYTHONPATH is set

echo $PYTHONPATH

Specifically did you use the pip3 or python3 -m pip commands as root?
Why I ask is that if you did that has a good chance of messing up system python.

Another thing you can try is to add a new user to your system and try mock from that user. If that works then there is something in your environment that breaks mock.
