macOS Playgrounds 4.2 fails cannot build swiftui

On macOS 13.0 (M1 Mac Book Pro), downloaded Playgrounds 4.2, and selected one of the new app playgrounds e.g getting started with Apps, or just a simple new app. A list of errors is immediately produced, and no preview can be seen:

What could be causing this ?

I just tried this here in my office and it’s working for me. Specifically:

  1. On macOS 13.0, I updated the Swift Playground app to version 4.2.

  2. I launched the app and chose File > New App Playground.

  3. I waited a bit, and the preview rendered as expected (see the screen shot below).

That’s what you did, right?
