memory leak help

I need help. I have a SpriteKit Scene and use the update function for changing a property of the Scene. This property is used for a Circle View in the ZStack. When I am tapping the Button, there is a memory leak detected in the leakage tool of Xcode. Is this a bug or why could this happen? The button only is printing something on the console.

Code Block 
import SwiftUI
import SpriteKit

Code Block 
 class Game: SKScene, ObservableObject{
		@Published var lenght: CGFloat = 1
		 var up: Bool = false
		 func change(){
				if self.lenght > 200 {
						up = false
				}else if (self.lenght < 5){
						up = true
				}
				up ? (self.lenght += 1) : (self.lenght -= 1)
		}
		override func update(_ currentTime: TimeInterval) {
				self.change()
		}
}

Code Block 
 struct ContentView: View {
	 @ObservedObject var game = Game()
		var body: some View {
				ZStack{
						SpriteView(scene: game)
						Circle().frame(width: game.lenght, height: game.lenght)
								.foregroundColor(.white)
						Button("hello"){
								print("hello")
						}
						.frame(width: 50, height: 20)
						.foregroundColor(.black)
						.background(Color.blue)
				}
		}		 
}

The Leak is: NSXPCConnection remoteObjectProxyWithErrorHandler

If I change the button to:

Code Block 
 Button("hello"){
		print("hello")
		game.lenght = 30
 }

then there is appearing this library between the QuartzCore in the Malloc 64 Byte entry:

"AXCoreUtilities"

I really hope that there is anybody who knows what's going on here. Thanks for any answers.
