在我的SwiftUI应用程序上，正常导航会导致我感到奇怪的崩溃

我有一个简单的标签视图：

struct FFTabView: View {
    var body: some View {
        TabView {
            libraryView2()
        }
        .navigationBarBackButtonHidden(true)
        .navigationBarHidden(true)
        .navigationBarTitle("",displayMode: .inline)
    }
}

// MARK: -

struct libraryView2: View {

    var body: some View {
        VStack {
            NavigationLink(destination: Foo()) {
                Text("go to foo")
            }
        }
        .tabItem {
            Image(systemName: "square.grid.2x2.fill")
            Text("Skill library")
        }
    }

}

struct Foo: View {
    var body: some View {
        Text("foo view")
    }
}

当我通过导航栏返回时，从Foo崩溃：Tried to pop to a view controller that doesn't exist

知道这里发生了什么吗？我找不到与此和SwiftUI相关的任何内容，因此我想发布。谢谢
