Annoying, isn't it? I had the same issue when I updated to 1909. It would be nice if Asus would update the SSII driver they gave us. Fat chance.
However, in order to solve the issue you posted above, you can go to the file that is shown in the UAC dialogue above, rt-click on it, then go to Properties > Compatibility tab, and go to the bottom and click on "Change Settings for All Users". At the bottom of that new dialogue check the option for "Run this program as an Administrator", and then OK to all that. When you reboot you won't see it again.
You will need Administrator privileges on your login credentials in order to make this change.
If I remember correctly my SSII desktop launcher icon disappeared for me after I did that, so I had to copy that one over from the Start menu. Give it all a shot and let us know if it worked out for you.
I have tried setting it to run as admin but when I do that the program doesn't start up with windows anymore?
maybe I can create a new task to start it with windows.
