Hi, sorry for late reply on this issue. This appears to be a problem with missing packages on your system, please try installing them
sudo apt install xapp-sn-watcher libxapp-gtk3-module xdg-desktop-portal-xapp xdg-desktop-portal-xapp-dt

Confirm the bug with Linux Mint 21.3
Sometimes app starts, sometimes not (via menu). But via terminal it runs almost everytime and it's always Gtk-Message: Failed to load module "xapp-gtk3-module"

sudo apt install xapp-sn-watcher libxapp-gtk3-module xdg-desktop-portal-xapp xdg-desktop-portal-xapp-dt

So looks like these are obsolete libraries xapp ...
