SwiftUI DatePicker on MacOS crashes on run – is it just me?

Solution for SwiftUI DatePicker on MacOS crashes on run – is it just me?
is Given Below:

Converting a small MacOS form style app to a MacOS SwiftUI app. I added a DatePicker and the app started crashing. Reduced it to the following reproducible minimum code. If either of the .padding() or the Text(“Second Row”) is removed or commented out. The app loads OK. Anyone with greater experience provide some assistance ? In case it is relevant this on being done on Catalina 10.15.7, Xcode Version 12.4 (12D4e).

import SwiftUI

struct ContentView: View {
  @State var thisDate: Date = Date(timeIntervalSinceNow: 0.0)
  var body: some View {
    Form {
      VStack {
        HStack {
          DatePicker("Pick", selection: $thisDate)
            .padding()
        }
      }
      Text("Second row")
    }
  }
}

In the app, the crash record shows that it is whilst it is trying to do the layout but as this case, it is during the app startup process.

I am having the same problem. It worked in earlier versions of my app. The View where this happens has not changed from the time it did work. Something outside of that view may be causing the problem.
