Upgraded to Ubuntu 19.04 recently, and now when I drag an image file from a Files window or Geeqie to my rawproc desktop shortcut, the little folder thingee just flies back to the image’s icon. Google did not render wisdom for this, looking for a solution, or at least insight…
Are you perchance using KDE?
Google may not work, but Duckduckgo does:

Are you sure you weren’t d&ding from the desktop? It should work fine from the Nautlus/Files.
The short version is that Gnome removed desktop icons. Ubuntu added them back with an extension. The extension doesn’t allow you to drag from nautilus to the desktop. I believe I read that the author of the extension stated it would take changes to mutter(the window manager of gnome) to allow that to happen.
Yes, and you can’t drag from the desktop to any other app atm.
That sounds about right; i couldn’t find any bug reports on it. So. I may have to start contributing to (or fork?) mutter…
Here is some information for reference.
