That is a Debian packaging of gnuradio bug that mint inherited.
This is also found in Debian 10 "Buster" gnuradio 3.7.13.4-4.

The problem comes from Python byte-compiled files used as templates.

The solution is to remove all .pyc files found under
/usr/share/gnuradio/modtool/gr-newmod
especially:
/usr/share/gnuradio/modtool/gr-newmod/python/build_utils_codes.pyc
/usr/share/gnuradio/modtool/gr-newmod/python/build_utils.pyc
/usr/share/gnuradio/modtool/gr-newmod/python/__init__.pyc

I missed these becasue they are not present in the .deb, but are
generated when the package is installed.

Recent (gnuradio 3.8) Debian packages no longer byte-compile any Python
under /usr/share/gnuradio/ - solving this problem.

Easiest fix is just
`sudo rm /usr/share/gnuradio/modtool/gr-newmod/python/*pyc`

Good luck,
