It's actually a bit stranger for me. When I choose "Set as Background Image" the window to set the background image comes up but the window is empty (Screenshot attached). Then when I change the option in that window from "Tile" (the image shows up in the window) and then back to "center" the image shows up like it should in the window, but still clicking the the "set Desktop background" button does not work.
Note that setting the background image via Appearances preferences does work fine.
