It could be an issue with the Sonoma beta, hence the question.  If you can, try it on a Ventura host.

And a big second on using the utility to get the ISO instead of uuddump - you'll get the latest and greatest build with that.  Also, I'd tried upgrading an existing Win11 Fusion 13 VM and had all sorts of issues.  Building a new one from scratch solved all of them.
