Fixing a Popup App:
Two steps...
1. Exiting this App:
Use the following to exit the app and get to Finder the (Smiley face). [command+tab] Use it to Access your Mac when Something is Not Responding
2. Remove Login items:
Now that you are in Finder, see if Notes is a Login Item. If so, remove is as such and then restart the Mac, seeing if this no longer occurs. Go Here: Change Users & Groups Login Items Preferences on Mac - Apple Support.
