Yes:

- GRASS GIS 7.6 uses Python 2
- GRASS GIS 7.8 uses Python 3

Here I didn't get that error but mainly the one with the wrong
formatting. The "... not found" might be a secondary error while the
original error message isn't visible (for whatever reason).

Let me suggest that you update all Python script to Python 3 (there is
the "2to3" script as well as "autopep8" and others for that purpose).
Once done, perhaps the errors you get are gone?
