This is no help at all

- The compatibility Matrix states Horizon 8 (2106) is compliant with Windows version 21H2 - that's what I'm running.

- I originally had Horizon 7 running on Win 10, and upgraded to win 11 - everything worked perfectly.

- The issue began when I got a popup telling me to update my Horizon version from 7 to 8: this was when VMWare failed at everything it supposedly supports. 

- No one - NO ONE - has answers. 

It has become clear there are quite a few people who have similar issues, and VMWare failed to effectively test their product in this new environment - an imbecilic failure on their part, given the inclusion of Win11 21H2 in their compatibility guide. There are no aids, guides, or support articles for this failure.
