If it's not 3.6 or 3.8 then I'm lost

Are you sure you have python 3.8? Actually, 3.9 would be ideal but 3.8 should work for now.
Run this on the terminal:
python3 --version

Check the log. It says python 3.7.1 was found. We checking for python which points mostly to python2 and python3. Maybe legendary supports setting the python path or atleast looks also for python39? If so we could implement that, too
