Windows 11 Update Failed, then Windows Update failed

Here's a possible explanation of what I've been experiencing. As those who have been following this discussion know, after attempting to upgrade to Windows 11 under the Release Preview Channel of Windows Insider (an opportunity that I was offered in Windows Update and which also appeared in notifications) I was unable to achieve any result, and thereafter I got errors when trying to use Windows Update. I decided to drop out of the Windows Insider program temporarily. I rebooted and voila! Windows Update was again available. I re-joined the Release Preview Channel of Windows Insider, rebooted, and updates were still available and (at least as of now) I am not offered the chance to upgrade to Windows 11.  Perhaps Microsoft invited my upgrade prematurely?

I just ran the Windows Update and got the attached file.  Dare I do this again?  (I've seen this same upgrade offer many, many times now, and running it will likely cause errors in my getting future non-upgrade updates.)
