Thanks for your response.
In terms of the version of Windows it's using the Windows ADK 2004 and amd64 architecture. Below is from the details from the DIM log file.
"Target image information: OS Version=10.0.19041.208, Image architecture=amd64"
I was able to run the update (KB4598481) that you recommended above, and it ran successfully. Following that I tried running the Cumulative Update released on March 15th (KB5001567) and got a new error code " Error:0x80070002 "
Here is a summary from the DISM log file of the related events around that error code:

I then realized that maybe I had installed the wrong March Cumulative update when I re-examined the list for March updates, realizing there was one released on March 8th before the March 15th one, and attempted to install this cumulative update (KB5000802)
I got the same "Error:0x80070002" result. I looked up this error code and saw it's something with the Windows Update not being able to be applied, but most items seem to indicate a resolution by booting up the computer and manually installing via Windows Update. Since this is for an image build process, I want to install these updates via DISM.
Any suggestions on what I need to be doing to get the updates installed? Did I install the wrong Cumulative Update after successfully installing the Servicing Stack Update KB49598481?
Any help is appreciated. Thanks again for your earlier reply and assistance.
