重新启动终止的活动后，我的应用程序崩溃，该活动使用多个后退堆栈，如samples中底部导航标签所示。仅在使用多堆栈时崩溃。

抛出异常的行：
private static Event downEvent(State state) {
switch (state) {
case INITIALIZED:
throw new IllegalArgumentException();
依赖项：
const val navigationFragment = "androidx.navigation:navigation-fragment-ktx:2.3.0"
const val navigationUi = "androidx.navigation:navigation-ui-ktx:2.3.0"
设置代码：
binding.bottomNavigation.setupWithNavController(
listOf(
R.navigation.nav1,
R.navigation.nav2,
R.navigation.nav3
),
supportFragmentManager,
R.id.container,
intent
).observe(this) { controller ->
navController = controller
controller.addOnDestinationChangedListener(this)
}
Xml（也尝试过<fragment/>）：
<androidx.fragment.app.FragmentContainerView
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="androidx.navigation.fragment.NavHostFragment"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
