Have just updated EN to 10.19.2 for Mac this morning. I was searching for some note (from search bar in Home page). Now EN seems caught in infinite loop. Finder does not like it and sends window "Window is not responding. -- Keep waiting or Relaunch". Waiting or Relaunching does not help. When I close EN and re-open the app, it shows the Home page and tries to show search results but loops infinitely again while freezing the screen so that I can not remove the search criteria. No button on Home page reacts to clicks or keyboard. Any idea from the EN community?
