Source image is 19042.631, which is not the 20H2 RTM or GA builds (508 or 572). Maybe the error would go away if you tried the original 20H2 ISO, before integrating your updates.

If you're using a later build (usually from MSDN or Insider), it means some updates already integrated. They are working images, but applying updates or removing features can lead to weird problems not seen with RTM. I'm not saying that's happening here, but it's easier to compare notes when everyone begins from the same image.
If you're using the current NTLite, and this problem happens again -- report it to nuhi.
