Navigate to another subview from tabbar which is a subview

Hello,

i have a mainview which is a list of customers, by NavigationLink i go the a detailview which is a tabview.
On the second tab i have a another list with a navigation link where i go to a another detail view.
This works fine, but when i try to go back to the tabview page from the detail view i got following error:
'Tried to pop to a view controller that doesn't exist.'

does anyone have a solution how I can add more detail views to the NavigatioView from a detila view?

MainView:

NavigationView {
            List(data, id: \.id) { item in
                NavigationLink(destination: ViewCustomersTabBarDetail(customerID: item.id)) {
                   
                    HStack {
                        VStack {
                            HStack {
                                Text(item.cnr)
                                    .font(.system(size: 12))
                                    .foregroundColor(.gray)
                                Spacer()
                            }
                          
                            HStack {
                                Text(item.name)
                                    .font(.system(size: 14))
                                Spacer()
                            }
                        }
                        Spacer()
                    }
                }
            }
               
            .navigationBarTitle(Text("Kundenübersicht"), displayMode: .inline)
            .navigationBarItems(leading:
                Button(action: {
                   
                }) {
                    HStack {
                        Image(systemName: "arrow.left.circle")
