I am using Evernote for Windows 10.12.6-win-ddl-public (2583) and it keeps popping up a small window with no text in it, only a black pane, even when the app is closed. I'm assuming it's trying to ask me if I want to upgrade to a new version but I can't do anything because it's not displaying any text or buttons. When I open Evernote and ask it to check for updates, I get a very very similar blank window. Changing my dark mode setting from "use system default" (which gives me dark) to "light mode" only changes the background color of this pop-up from black to white; there is still nothing visible. What can I do to fix this?
