Missing argument for parameter 'backingData' in call

I am using SwiftData in a SwiftUI view called DeckView and I'm adding a AddDeck function but let deck = Deck() is returning 'Missing argument for parameter 'backingData' in call' Here is the full code:

DeckView

import SwiftUI
import SwiftData

struct DeckView: View {
    @State private var showingSheet = false
    @Environment(\.modelContext) var modelContext
    @Query var decks: [Deck]
    @State private var path = [Deck]()
    
    var body: some View {
        NavigationStack(path: $path) {
            ZStack {
                Color.background
                    .ignoresSafeArea()
                
                List {
                    ForEach(decks) { deck in
                        NavigationLink(value: deck) {
                            HStack {
                                VStack(alignment: .leading) {
                                    Text(deck.name)
                                    HStack {
                                        Image(systemName: "square.3.layers.3d.top.filled")
                                        Text(deck.cards)
                                    }
                                    .padding(.top)
                                }
                            }
                        }
                    }
                    .onDelete(perform: deleteDeck)
                    .listRowBackground(Color(.secondaryC))
                }
                .scrollContentBackground(.hidden)
            }
            .foregroundColor(Color(.text))
            .navigationTitle("Decks")
            .navigationDestination(for: Deck.self, destination: EditDeckView.init)
            .toolbar {
                ToolbarItem(placement: .topBarTrailing) {
                    Image(systemName: "plus")
                        .onTapGesture {
                            showingSheet.toggle()
                            addSamples()
                        }
                }
            }
            .sheet(isPresented: $showingSheet) {           
                CreateDeckSheet()
            }
        }
    }
    
    func addSamples() {
        let swiftd = Deck(name: "SwiftData", cards: "20")
        let swifty = Deck(name: "Swift", cards: "21")
        let swiftyui = Deck(name: "SwiftUI", cards: "32")
        
        modelContext.insert(swiftd)
        modelContext.insert(swifty)
        modelContext.insert(swiftyui)
    }
    
    func addDeck() {
        let deck = Deck()
        modelContext.insert(deck)
        path = [deck]
    }
    
    func deleteDeck(_ indexSet: IndexSet) {
        for index in indexSet {
            let deck = decks[index]
            modelContext.delete(deck)
