导航组件对话框片段 NoSuchElementException

Question

底部导航栏中有 3 个片段

-> 第三个片段有一个 viewpager2，其中有 2 个片段。

-> 单击 viewpager 的一个片段中的按钮会打开 BottomSheetDialogFragment，并在该 BottomSheetDialogFragment 中完成几个步骤后

-> 该片段被关闭并打开另一个 BottomSheetDialogFragment。

当最后一个 BottomSheetDialogFragment 关闭时，应用程序崩溃并出现以下错误

java.util.NoSuchElementException: Collection contains no element matching the predicate.

我一个月前升级到导航库 2.4.0-alpha03 并忽略了这个问题，认为它在 alpha 中并且会被修复，alpha05 已经出来并且仍然相同，我决定转到稳定版本 2.3 .5 并且错误仍然存​​在。

这是 gradle（模块）

apply plugin: "androidx.navigation.safeargs.kotlin"

implementation 'androidx.navigation:navigation-fragment-ktx:2.4.0-alpha05'
implementation 'androidx.navigation:navigation-ui-ktx:2.4.0-alpha05'

gradle（模块）

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.4.0-alpha05"

导航图如下所示

    <fragment
        android:id="@+id/profile"
        android:name="com.example.user.profile.ProfileFragment"
        android:label="Profile"
        tools:layout="@layout/fragment_profile">
        <action
            android:id="@+id/action_profile_to_editProfileFragment"
            app:destination="@id/editProfileFragment"
            app:enterAnim="@anim/from_right"
            app:exitAnim="@anim/to_left"
            app:popEnterAnim="@anim/from_left"
            app:popExitAnim="@anim/to_right" />
        <action
            android:id="@+id/action_profile_to_predefinedHabitsFragment"
            app:destination="@id/predefinedHabitsFragment" />
        <action
            android:id="@+id/action_profile_to_editHabitBottomSheetFragment"
            app:destination="@id/editHabitBottomSheetFragment" />

    </fragment>

    <dialog
        android:id="@+id/addPredefinedHabitBottomSheet"
        android:name="com.example.habits.add.predefined.AddPredefinedHabitBottomSheet"
        android:label="AddPredefinedHabitBottomSheet"
        tools:layout="@layout/add_predefined_habit_bottom_sheet">
        <argument
            android:name="habitData"
            app:argType="com.example.predefined.models.PredefinedHabitsModelItem" />
    </dialog>

    <dialog
        android:id="@+id/addCustomHabitBottomSheet"
        android:name="com.iku.habits.add.custom.AddCustomHabitBottomSheet"
        android:label="AddCustomHabitBottomSheet"
        tools:layout="@layout/add_custom_habit_bottom_sheet" />
