correction, it was not the theme, but the style that I changed in the
options.
I now manually changed back the value for style to default in the
QGIS3.ini file, and now everything seems to be back and working.
Loosing all settings because that stuff would have been not so funny!
Is it possible
Hi,
just for fun I wanted to change the theme. When doing so, a python error
window was shown, but had no content but a duplicate of the canvas. Then
everything froze.
I was able to restart once. Fumbling again in the theme setting led to a
sudden crash, and QGIS could not be restarted.
