I experienced something similar to Gary56 after the most recent update to Windows 10 Build 19043.867. I know he is on 19042.867, but they are the same code base. Deskscapes Configuration would not even open for me.
I uninstalled Deskscapes 10.03, ran the purge bat, and reinstalled with a new installer downloaded from my account. All seem to be well so far.
