More drama please.
I am guessing here, but it can be an actual feature removed due to Nautilus rework Gnome people made or, since launching applications require some permissions, it has been prohibited due to Wayland adoption.
I had the same problem once using an desktop icon created by myself. I double clicked it to give permission and the icon changed
EDIT: @Norbert if it worked let us know
@Alculete Yes, it works after clicking Trust and Launch
but this solution is not intuitive, not expected and unnecessary action for default pre-installed desktop-files.
Not expected maybe, unnecessary not, since it’s a security control
