Can't get the "Validate App" button to activate for building an Archive

The Validate App button remains grayed out on XCode 14.3 when I build an Archive. This is a brick for me. I can't submit my app to the App Store. Ideas, please?

MacOS 13.3, iOS 16.4, watchOS 9.4.

If it makes a difference, I'm running an OCLP version of Ventura on my 2014 Retina 5K mac...

TIA.
