Double-clicking desktop folder opens geany editor instead of clicked folder

When double-clicking a folder icon on the desktop, I expect that folder to be opened in a file browser. On my system, the geany editor is opened instead. Uninstalling geany solves the problem. Re-installing nautilus and geany does not solve the problem. Environment: * Ubuntu 20.04.3 LTS * Gnome 3.36.8 * geany 1.37.1-2~16.04 * Nautilus (aka files) 3.36.3-stable Any help resolving this problem will be highly appreciated.
