GNOME Bugzilla – Bug 786908
Ctrl+N shortcut does not work when desktop has focus

The bug has been reported on https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1710931 and is confirmed with nautilus 3.25.90/GNOME/wayland "When a Nautilus window is open, Ctrl+N opens a new window that shows the same folder as the focused Nautilus window. However, when the desktop is focused, the shortcut doesn't work - instead I see an error that x-nautilus-desktop:// is not supported."
Can confirm.
Starting with version 3.28, nautilus will not handle the "files on desktop background" feature. For better alternatives, read this blog post https://csorianognome.wordpress.com/2017/12/21/nautilus-desktop-plans/
NB: above link doesn't provide any solutions for users, just developer plans to further limit nautilus's usability. Ctrl-N will continue to produce that x-nautilus-desktop:// error, and there's no-one at gnome who will fix it. "Status: RESOLVED OBSOLETE" == "we hate users".
