Xamarin.Forms - Navigation.PushAsync "Only the original thread that created a view hierarchy can touch its views"

Question

Hey!

I have a page with a barcode scanner in which another page is opened when a scan is completed. I use Navigation.PushAsync, which works everywhere in the app, but somehow it doesn't work here and throws the exception "Only the original thread that created a view hierarchy can touch its views". I have no idea how to fix this, so hopefully someone is able to help.

The interface:

Opening the page (simplified):

The error occurs at line 127. I hope someone can help!

await Navigation.PushAsync...
});
