When first I run GRASS GIS 7.6.0, there is an error message :

(gis_set.py:4772): Gtk-WARNING **: 16:05:43.648: Theme parsing error:
gtk.css:2:33: Failed to import: Error opening file
/home/mega/.config/gtk-3.0/whisker-tweak.css: No such file or directory

I ignore the message. I start GRASS GIS. I import raster and vector. I add raster as RGB.

Image is displayed in map display window. Then I choose Imagery > classify image > Interactive input for supervised classification. Then GRASS GIS supervised classification tool appear.
But, no image in training area display and preview display. Then I import training area from vector map.

Suddenly, all window GRASS GIS quit except GRASS GIS terminal window.

So, how to solve this problem? I run in MX Linux 19.
