SwiftUI - Realm: Cannot remove an observer for the key path from because it is not registered as an observer

I'm facing a weird issue with the latest Realm Release 10.6.0. When I'm trying to delete an object that is used across multiple NavigationViews I run into the error:

Cannot remove an observer <RealmSwift.SwiftUIKVO 0x6000000c00e0> for the key path \"myId\" from <RLM:Unmanaged MyModel 0x6000037fa8a0> because it is not registered as an observer.

I assembled a super easy Demo Project to reproduce the error. Just run this and go to the third View where you wanna click on the button before you try to navigate back.

import SwiftUI
import RealmSwift //minimum version 10.6.0 Realm and 10.5.0 RealmDatabase from https://github.com/realm/realm-cocoa

//MARK: - Realm Model

@objcMembers class MyModel: Object, ObjectKeyIdentifiable {
    dynamic var myId = ""
    dynamic var text = ""
    dynamic var desc = ""
    
    override static func primaryKey() -> String? {
        return "myId"
    }
    
}

//MARK: - Root View

                Text("Click the plus in the toolbar to add some test entries")
                
                List {
                    ForEach(myModel) { model in
