Как найти причину java.lang.IllegalStateException?

Question

в Google Play Console мне пришло уведомление о сбое моего небольшого приложения на устройстве Xiaomi Mi 10 (код ниже). Я в Android Studio все проверил много раз, но таких сбоев не нашлось. Как я могу узнать откуда он? Спасибо.

Одна из причин возникновения этой ошибки это использование parentFragmentManager вместо childfragmentmanager. Ошибка происходит во время поворота дисплея и уведомление об ошибке полностью идентично вышеуказанному. Нужно использовать childfragmentmanager. Однако в моем случае в манифесте с самого начало было отключено изменение ориентации android:screenOrientation="portrait". Следовательно, данная ошибка не должна была быть. Я поменял на childfragmentmanager, если заново придет уведомление, значит проблема в чем-то другом.

 override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View?
    {
        val root = inflater.inflate(R.layout.main_layout, container, false)
        val tablayot = root.findViewById<TabLayout>(R.id.myTablayout)
        val viewPager2 = root.findViewById<ViewPager2>(R.id.myViewpager)
        val adapter = MyPageAdapter(childfragmentmanager, lifecycle)
        viewPager2.adapter = adapter
        TabLayoutMediator(tablayot, viewPager2)
        {
            tab, position ->
            when(position)
            {
                0 -> {tab.text = "FirstPage"}
                1 -> {tab.text = "SecondPage"}
                else -> {tab.text = "MainPage"}
            }
        }.attach()
        return root
    }
