I set up my development environment on Fedora 35 and when I run any brownie command such as $ brownie console or even brownie --version I get the following error:

I have spent a whole day trying to fix this error, please help me out!
The problem here seems to be Python 3.10.1!
I used anaconda to create a new virtual environment with Python 3.8.12, installed brownie using pipx install --python python3.8 eth-brownie and it worked!
The trick here was, to also tell pipx to use another python version, otherwise it would create a dependency to the global python version, which is python 3.10 in my case.
