Lots of issues.

1) My critical VM is gone!  For no known reason, when I open Fusion 12.2.5, it says "Virtual Machine does not exist."  Well, it existed last week, and the week before, etc...

2) I have a backup in a /restore directory on my Mac, where an earlier version of my VM exists.  When I try to import that, the VM image is greyed out in the Fusion console.  If I view the same VM in my Mac Finder, it is not greyed out, the properties are in order, and I can expand the image and see the contents.  Fusion is definitely the blocker here.

3) When I try to create a new image from the original Windows 10 iso in Fusion, I get a little farther - the ISO is recognized.  But when the installer starts, it can't find the operating system ?!?!

At this point, Fusion is really not doing me any good!
