Some, not all of the permanent icons I keep on the desktop keep on disappearing.
Refresh desktop will not get then back.
I have to open the desktop folder in file explorer to find them.
The only want I can get a folder icon back on the desktop is to drag the folder from the desktop folder in file explorer into a new folder then drag it out onto the desktop.
But after a while the icon disappears again.

Why are icons disappearing?

Any idea how to keep them on the desktop.
