Windows 10: Installing KB4517389 causes critical error when accessing the Start Menu

Installed KB4517389 and I get a Critical Error message every time I try to access the Start Menu. (see below)

Operating System: Win10 Home, version 1903, installed 6/4/19.


1. If I uninstall this update, the problem goes away.

2. I tried reinstalling this update, but the same problem occurs.

3. Even in Safe Mode with this update installed, the Start Menu won't work.

4. I've even tried temporarily disabling my antivirus to see if there was some sort of incompatibility. It makes no difference.


For the moment, I have uninstalled KB4517389, but this is not a good thing to do.
