I've just upgraded to OS X Mojave on a late 2015 MBP Retina. Every time I open system preferences to change the desktop image, system preferences hangs and then crashes. Even selecting an image in finder and right clicking 'set desktop image' results in nothing.
MacBook Pro with Retina display, macOS Mojave (10.14)
Safe Mode boot deletes system caches that can help after a macOS update or upgrade.
To start up in safe mode:
To leave safe mode, restart your Mac without pressing any keys during startup.
Then try changing the desktop image.

HI Carolyn, unfortunately this hasn't worked. I have noticed however that when plugged into an external monitor, a desktop background is present on that, just not the actual laptop. Also, before becoming unresponsive the desktop section in system prefs shows this:
