I'll post a fix later.

I've uploaded a file - atdaa.zip - to my OneDrive at Noel's OneDrive
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract to the default location - which will create a new folder atdaa in the same place.
Open this folder - there should be two folders inside it (Manifests, and Packages)

Copy the content of the Packages folder to the folder
C:\Windows\Temp\CheckSur\Servicing\Packages

And the content of the manifests folder (.manifest files) into this folder:

C:\Windows\Temp\CheckSur\Winsxs\Manifests

Now run the CheckSUR tool again (it may take a while)

Post the new CheckSUR.log file, and the CheckSUR.persist.log file.

Sorry - must have forgotten to create the link...

... so it looks like all problems there are fixed

With luck Windows Update will work now - do a Check for Updates, and attempt to install ONLY the oldest found update - what happens?

Nope - this error is usually got around by using the standalone installer (I assume that you used Windows Update this time?)

Try the standalone, and with luck it'll work.
