Prusa Slicer 2.3.3 Failed to Load modules
We are getting errors when Prusa Slicer starts up and would like to know how to fix them?
Recently Prusa Slicer 2.3.3 failed to show the plater. We are runing PopOS which is derived from Ubuntu 20.04 LTS. PrusaSlicer-2.3.3 is loaded from the Pop Store Flatpak. It worked well all Summer, or so I thought. Uninstalling and reinstalling brought the plater back. Though I did uninstall and reinstall nvidia drivers before trying reinstalling PrusaSlicer so they may be related.
During this process we ran PrusaSlicer from the terminal using "flatpak run com.prusa3d.PrusaSlicer" and received the following errors:
flatpak run com.prusa3d.PrusaSlicer Gtk-Message: 11:36:41.207: Failed to load module "appmenu-gtk-module" Gtk-Message: 11:36:41.293: Failed to load module "canberra-gtk-module" Gtk-Message: 11:36:41.293: Failed to load module "canberra-gtk-module"
There were more warnings and critical errors afterwards related to the modules that failed to load.
Tried to install appmenu-gtk-module and canberra-gtk-module and the are not found. However appmenu-gtk2-module, and appmenu-gtk3-module are already installed on my system. I also have libcanberra-gtk-module installed. These errors occured both when the Slicer stopped displaying the Plater and later after reinstalling and getting the Plater to appear again.
