Pressing Command+Tab to switch between open applications works fine except it does not show me the default Finder App anymore.
I tried to reboot the laptop but still same issue. Of course if I click the Finder App directly from the Dock, the Finder Window open but still even with the Finder Window open, if I press Command+Tab I still can not see the Finder App icon among the current running applications.
This is not a managed device, is my personal laptop without any managed profiles installed.
I did not run any command line to hide anything.
