"Application Menu" missing on Desktop after KDE/Plasma update from 5.16.5 to 5.17.4

[Dan Johansson <kde@xxxxxx>]

After updating KDE/Plasma from 5.16.5 to 5.17.4 "Left Button" 
(Application Launcher) does not work anymore. Nothing happens when I 
"Left Click" on the Desktop. The other actions ("Right Button", "Middle 
Button" and "Vertical Scroll") works as they should.



This happens on two machines of mine (the two with KDE/Plasma).



This is really annoying as this is the main way I launch new programs.



Any suggestion?
