I installed multiple snap apps in Kubuntu 19.10 which functioned normally for a couple of weeks until today. Now when I open snap apps from the dock, icons have a question mark and when opened, the error message is:
Unknown application folder
When I search for the snap apps in the menu, none show. However, when I do
snap list, all the snap applications are listed. In the terminal, kdenlive appears to be installed. When I search for the application, it doesn't appear, only the snap directory for the application appears.
How may I troubleshoot this?
