After crashing duplicate identical windows are opened

Hello!

On visionOS, after an app with multiple scenes defined crashes and is re-launched, two windows are opened with identical contents.

Please see below for a minimal example:

struct SecondaryWindowTag: Codable, Hashable {}

enum WindowTag {
    static let secondaryWindow = SecondaryWindowTag()
}

@main
struct SwiftUIExampleApp: App {
    @Environment(\.openWindow) private var openWindow

    var body: some Scene {
        WindowGroup {
            Button {
                openWindow(value: WindowTag.secondaryWindow)
            } label: {
                Text("Open Window")
            }
            .buttonStyle(.bordered)
        }

        WindowGroup(for: SecondaryWindowTag.self) { _ in
            Button {
                fatalError("Test crash")
            } label: {
                Text("Crash")
            }
        }
    }
}

Here is a screenshot taken after re-launching following a crash. You can see there are two windows both having the "Open Window" button of the first WindowScene defined above.

Is this a known issue? Are there any workarounds I could try?

Thank you!
