To provide further information/context. We on the ProSeries engine team worked directly with Microsoft about this issue specifically so I can confirm that we did in fact get an early release of the fix and established that the patch did fix the issue. Once its released I am certain it fixes the issue as we have already tested it. 

As for allowing Microsoft to do anything, we are not really in any position to allow or disallow any patches they push. 

I can however assert that it was with the help of the people on this community that we were able to act quickly and decisively concerning the issue and present Microsoft with evidence that their update did in fact cause the issue. And for that I thank you. Your assistance helped everyone who is using ProSeries and upgraded to Windows 11.
