Hello,
trying to start grass with the GUI results in the following traceback
--8<-----------
Launching <wxpython> GUI in the background, please wait...

and the GUI not starting.
I have found an issue on the osgeo trac
https://trac.osgeo.org/grass/ticket/4015
that seems to indicate the issue is actually in the Python 3
interpreter.
Best regards,
