Why doesn't hotkey service start on Mac OS?

Question

macOS

Good day!
I need to quickly turn off the microphone. Set up a service in Automator that calls AppleScript:

Screen

The code

on run {input, parameters}
  
  set inputVolume to input volume of (get volume settings)
  if inputVolume = 0 then
    set inputVolume to 100
    set displayNotification to "Microphone Unmuted"
  else
    set inputVolume to 0
    set displayNotification to "Microphone Muted"
  end if
  set volume input volume inputVolume
  
  display notification displayNotification
  delay 1
  
  return input
end run

Created a hotkey for this service in the keyboard settings

From this menu everything works as it should.

From the "system settings" the hotkey also works, but from other places (Finder, browser, etc.) it does not work in any way.
How can I make it work everywhere, not just in settings?
