@sdetweil Well that sorted it. Thank you so much.

I’m using Arch Linux (Gnome desktop)
MagicMirror is the latest version and is up to date.
I ran npm start (without issues before this), and this is what I’m seeing.
I only use two modules, so I removed MagicMirror and reinstalled, same problem appears.

Gtk-ERROR **: 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported.
/MagicMirror/node_modules/electron/dist/electron exited with signal SIGTRAP.
