grass7 @7.8.3_2: crashes on start with wxWidgets 3.2

With the upgrade of wxWidgets to version 3.2, grass7 is failing already at start:

wxWidgets 3.2 typically follows a wxPython 4.1.0 installation (via pip). This move is premature for GRASS, which version 7.8.3 isn't ready for either. GRASS 7.8.4, soon to be released, will be.

wxWidgets 3.2 typically follows a wxPython 4.1.0 installation (via pip).

Correction: wxWidgets 3.1.4 follows wxPython 4.1.0

Working combo for GRASS 7.8.3 is: 4.0.7.post2 and wxWidgets 3.0.5.

Turned out I had GRASS_PYTHON set, which interfered and run GRASS with a non-macports python version. That might be an issue in itself, but this ticket may be closed. Sorry for the noise.

Glad you got it working!
