I think the message "Child name '' not found in GtkStack" is unrelated. Not sure what is it, but I doubt it is Pods fault.

When googling for "desktop entry Failed to register: Timeout was reached" I find a lot of related issues with other gnome apps.

Have you tried?

killall pods

and start the app again?
