I made a couple of changes and the hive corruption issue seems to be

The "RuntimeError: file receive cancelled by daemon" still persists. From
the guestfs trace I can't see any evidence if not what seems a sort of

sha1sum: ./Windows/Prefetch/ReadyBoot/Trace2.fx: Value too large for
defined data type
This kind of thing points to disk "corruption" (ie. an inconsistent
snapshot of a file that the guest is writing to). If the snapshot
isn't consistent you'd expect to see all kinds of strange errors --
the specifics don't matter, you'd just ignore the snapshot and move on
to the next.
"file receive cancelled by daemon" is a libguestfs bug because it
hides the true cause of the failure. It's quite hard to construct a
test case that reliably reproduces the bug however.
