Windows 10: All Windows Default Apps Won't Work, TWINUI

I can't start any apps on windows, such as the app store itself, the mail app, or Groove Music. Help would be much appreciated, the troubleshooter doesn't do anything and I already tried restorehealth in the command prompt.

TWINUI in place of some default apps


After upgrading several systems, on a couple of them I ran into an issue where instead on the standard Windows 10 default apps being listed for such things as Maps, Music Player, Photo Viewer, etc., "TWINUI" was listed. Fortunately it was easy to fix. All you have to do is open the standard default app, close it, go back to Settings, and it was miraculously fixed. It seemed to happen when going into a second user after the initial user setup completed and completing the setup for the second user.
