wxPython error when launching GRASS GUI

General

Pop OS 22.04
Grass 8.4 installed from Ubuntugis unstable

When I try to run GRASS from the desktop the GUI doesn’t open. Running the GUI from the command prompt returns an error related to wxpython.

g.gui wxpython
Launching <wxpython> GUI in the background, please wait...

I upgraded wxpython from 4.2 to 4.2.2 but it didn’t solve the issue.

pip3 list | grep wxPython
wxPython                4.2.2

Hi,

this looks like a problem with menu creation but I don’t know why would that happen, maybe you somehow modified your local settings?. You can try to rename ~/.grass8/ folder with all the settings to e.g. .grass8_backup and try if the GUI starts.

BTW, this is not the right place to ask this, either create an issue on GitHub - OSGeo/grass: GRASS GIS - free and open-source geospatial processing engine or subscribe and ask on grass-user mailing list, which hasn’t been transitioned to Discourse yet.
