After xCode Beta Update RealityView doesn't work anymore

Hello, Yesterday I updated xCode 15.2 Beta to 15.5. Now i tried to run my App but after starting i I recognized that when I open my volumetric window that the USDA scene in my RealityView doesn't file doesn't appear anymore. RealityView will be executed.+

When I use a 3D Model in my volumetric window the USDA appears without any problems. Here is my code:

import SwiftUI
import RealityKit
import RealityKitContent

struct MyWindow: View {


    var body: some View {


        RealityView { content in
            async let object = ModelEntity(named: "testScene", in: realityKitContentBundle)
            print("I exec")
            guard let object1 = try? await cloudyWeather else {return }
            object1.generateCollisionShapes(recursive: false)
            object1.components.set(InputTargetComponent())
            object1.location = .init(0,0.5,0)
            object1.scale *= 1




            content.add(object1)

        }.gesture(dragGesture)



    }

    var dragGesture: some Gesture {

        DragGesture()
            .targetedToAnyEntity()
            .onChanged { value in
                print(value.entity.name)
                value.entity.position = value.convert(value.location3D, from: .local, to: value.entity.parent!)

            }
    }
}
