Can't switch languages in Launchpad Mac OS
I have two languages in my System settings, and they switch correctly (with Cmd+Space keys) in every software I use. The only place where languages do NOT switch is Mac OS Launchpad (the search field on the top of the screen). To change the input language I have to swap to another (any) application, switch the language with Cmd+Space, then swap back to Launchpad.
The problem persists since 2016, from the very beginning I bought and set up my laptop.
How can I fix it?
