Windows 10 Update KB4532693 fails with error code 0x80073701

Hi,

I followed all the instructions in Windows Update Forum Posting Instructions and SFCFix doesn't find any problems (anymore) - "No corruptions have been detected on this computer.",
still Windows Updater will not successfully install KB4532693.

The progress indicator slowly goes up to "Installing - 44%", then jumps to 100%, and then the error 0x80073701 is shown. I tried this about 10 times over several days, did sfc ... and dism ... several times, to no avail.
This happens on Windows10 Pro x64, 1909, build 18363.535, running in a VirtualBox VM.

This is the contents of the CBS log folder:

(and for completeness, this is the output of SFCFix:

Hi!

The best way is to do an In-Place upgrade:

1. Download the Media Creation Tool and save this to your desktop. Go ahead and run this as well. Note: Click the Download tool now button when you get to this link.
2. Accept the License Agreement
3. Download the ISO file to your desktop.
4. Double-click on the ISO and then run the setup to try and upgrade your machine.
