Already filed a [[ https://gitlab.gnome.org/GNOME/gnome-notes/issues/122#note_423205 | ticket ]] upstream, but the dev got it running on PureOS.
On my machine it just fails with:
** (bijiben:18576): WARNING **: 09:20:05.978: Unable to connect to Tracker: Failed to load SPARQL backend: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

Starting from dash does nothing.
But starting it several times helps sometimes and waiting a little and hitting the superkey to see the app.
I have to add, that I'm using Gnome accounts with a Nextcloud instance attached.
