Comment 4 for bug 1890086

Please see the attached screenshot of me running pip show from the command line, as well as importing babel from in Python 3 on Mint 19.3.

I would guess that something has gone wrong with your install of Babel, for reasons I do not know.

Try this command, and then repeat once more to clear out any remnants (do not prefix with sudo):

python3 -m pip uninstall babel

then install again:

python3 -m pip install --user babel
