SwiftUI: Navigation Link аварийно завершает работу при повторном нажатии на iOS 14, но не на iOS 13

В настоящее время я работаю над приложением с функцией входа в систему, чтобы опробовать SwiftUI. Сбой происходит как на симуляторе, так и на реальном устройстве. Я могу войти в систему и перейти к следующему экрану. Однако, если я нажму кнопку «Назад» и вернусь к экрану входа в систему, произойдет сбой. Это единственный результат сбоя.

Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

Однако при работе на симуляторе iOS 13 сбоев не происходит. Я использую XCode 12.2, и сбой также произошел на 12.1. Вот код.

struct LoginView: View {

    @ObservedObject
    var loginViewModel: LoginViewModel
    
    @State var showSafari = false

    var body: some View {
        NavigationView {
            NavigationLink(destination: MainView(mainViewModel: MainViewModel(Fetcher: Fetcher())), isActive: $loginViewModel.successfulLogin) {
                Button(action: {
                    self.showSafari = true
                }) {
                    Text("Login")
                }
                .sheet(isPresented: $showSafari) {
                    SafariView(handler: loginViewModel.handler)
                }
            }
        }
        .navigationViewStyle(StackNavigationViewStyle())
    }
}

class LoginViewModel: ObservableObject, Identifiable {
    
    private let fetcher: Fetchable
    private var disposables = Set<AnyCancellable>()
    
    @Published
    var successfulLogin: Bool = false
    
    lazy var handler: LoginVCHandler = { [weak self] user, error in
        if let self = self, let user = user, let Id = user.ID {
            self.getPlayerSummary(Id: Id)
        } else {
            print("ERROR: \(error)")
        }
    }
    
    init(Fetcher: Fetchable) {
        self.Fetcher = Fetcher
    }
    
    func getPlayerSummary(Id: String) {
        fetcher.getPlayerSummary(Id: Id)
            .map { response in
                response.response.players
            }
            .receive(on: DispatchQueue.main)
            .sink(receiveCompletion: { value in
                switch value {
                case .failure:
                    print(value)
                    User.shared.cleareUserInfo()
                case .finished:
                  break
                }
            }, receiveValue: { [weak self] players in
                guard let self = self, let player = players.first else { return }
                User.shared.updateUserInfo(username: player.name, firstName: "", lastName: "", Id: Id)
                self.successfulLogin = true
            })
            .store(in: &disposables)
    }
}

Я рассмотрел другие вопросы, например Почему в моем приложении SwiftUI происходит сбой при переходе назад после помещения` NavigationLink` внутри `navigationBarItems` в` NavigationView`? и NavigationLink работает только один раз, в которых говорится, что проблема устранена, но не на основании того, что я вижу.

Вот трассировка стека, когда происходит сбой.
