Updated using sudo eopkg up, sudo eopkg up (just to be sure), sudo usysconf run -f, sudo sync, logout, hold power button.
Everything went well on 3 Budgie installations, one Gnome-Boxes installation. one on AMD cpu & gpu, and the last was Intel cpu & gpu.
Tried on a Solus Gnome installation in Gnome-Boxes, where I get an error "Oh no! Something has gone wrong", and are unable to log back in. Will reinstall it and try again. Had the following extensions installed: Arc Menu, Dash to panel, Show desktop button & Openweather.
