After opening jupyter-console in cmd, no matter what I input, I get the following unnamed exception. Any tips on what could be going wrong?

Unhandled exception in event loop:

See if the jupyter-client installed version is >= 8.0.0, in this case try downgrading to version 7.4.9:

python -m pip install jupyter-client==7.4.9 --upgrade

Don't know what's going on, but this solved the issue for me.

Note: I'm using MacOS Ventura 13.1 and python 3.9.6, but also checked on MacOS Catalina 10.15.7 and python 3.10 and downgrading jupyter-client solved the issue.
