I followed your instruction: quit, uninstall using AppCleaner, restart and install EN. Unfortunately it still doesn't work. EN keeps loading infinitely.
I think I have to download the legacy version. Although it doesn't work very well (as reported in https://discussion.evernote.com/forums/topic/143888-not-able-to-view-notes-in-full-screen-or-fit-to-page-on-mac-evernote-legacy-check-the-attachments-not-able-to-view-in-shaded-yellow-portion/), but at least it works.
