I'm considering that a workaround, not a resolution, fyi. I would like to keep my image updated, so this will still be hanging out there. I'm willing to collect logs if it's helpful.
I also received this same issue after I updated my reference image with the latest round of updates for Win 10 1903. Specifically, this was the 2019-07 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4505903).
