I don't know why I'm getting this error:
The items below are required to start the review process: New apps and app updates must be built with the public (GM) versions of Xcode 11 or later, iOS, macOS, watchOS, and tvOS SDKs. Apps built with beta versions aren’t allowed.
My macOS version is macOS Monterey 12.4 (21F79) and my XCode version is Version 13.4 (13F17a). I'm not running any beta software at all and I'm only using public releases.
