FOR INFO
I have just accepted the Hot Fix , and when I did the main update I saw the same behavior.
Some DLL’s do not have current security certificates and SmartApp shows a Notification saying so and stops the loading of that DLL.
For the main update it crippled Roon , this one at least Roon has started
The work around is easy just turn off SmartApps, Download the Correct Installer then install . Finally turn SmartApps back on
This is on Windows 11 Home fully up to date
