Left click (mouse or graphic pen) doesn't open Launcher

Hi guys,
As title, since some updates (I really can’t trace when it starts to do like this), I can’t run applications Launcher clicking on it.
It opens itself just using the META key.
Anyone else?
Is there a way to check if I’ve missed some key config or something else?

Thanks in advance

Just an update on this.
I’ve downloaded latest updates (quite big update) and now the Launcher opens itself clicking on it. Unfortunately, now the Discover notify icon stop working clicking on it.
