Azure Virtual Desktop - Black Screens on logins - What we've tried so far

To be fair that is basically the line I had from them - slightly different build numbers (but I think that was likely an error - the KIR references 5040525 in the file name) as they had said the July patch Tuesday build rather than July preview (for August' patch Tuesday) that they wanted us to uninstall... well having uninstalled KB5043064 and it reverted to KB5041580 we couldn't then get back past that anyway and their efforts to do so involved "editing it out" via the registry (which I am yet to be convinced wasn't just removing they systems knowledge of the patch existing for reporting/display purposes to make it look removed as winver still shows 4780 as the build number) which in the process totally screwed up the VMs; completely broke all local printers so no one can PDF any documents etc.

But basically that 3rd week October another way of saying it will be in the November patch Tuesday release - just you can have it in October for anyone brave enough to install a preview release onto a session host and risk jumping from the frying pan into the fire! (or am I just rather cynical of Microsoft's release testing these days 😂) - it won't be releasing tomorrow although I guess it might get mentioned on the known issues list; although at the moment they are doing a fairly good job at covering this up as it probably isn't a very good look for trying to sell AVD and FSLogix as a product to admit a regression originating in late July isn't going to be fixed for 3-4 months!
