Elements 2019 Organizer Instant Fix causes organizer to hang

Steps to reproduce:

1. Select a photo in the organizer
2. Click "Instant Fix"
3. Click "Done" (you don't even have to fix anything)

Expected results:

Should go back to the organizer.

Actual results:

The main window still shows the Instant Fix window, but is unresponsive. The menu will still open if you click on it, and File->Exit will close the window. But when I try to reopen the organizer, it won't open complaining that the program is already running. I have to reboot to be able to reopen the organizer.
