How to recreate from childFragmentManager?

Question

I am using a custom layout for my settings Fragment like this

class SettingsFragment : BaseFragment() {

    private var settings: FragmentSettingsBinding? = null

    override fun onCreateBaseView(
        inflater: LayoutInflater,
        parent: ViewGroup?,
        savedInstanceState: Bundle?
    ) {
        settings = FragmentSettingsBinding.inflate(inflater, parent, true)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        childFragmentManager.apply {
            popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE)
            beginTransaction().apply {
                replace(R.id.settings, Settings())
                commit()
            }
        }
    }

    open class Settings :
        PreferenceFragmentCompat(), Preference.OnPreferenceClickListener {

        override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
            setPreferencesFromResource(R.xml.preferences, rootKey)
        }

        override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
            super.onViewCreated(view, savedInstanceState)
           
            // recreate after some actions
       }
   }
}

Everything works fins until it come to recreate and than happens this:

I searched for similar cases and unfortunately, did not find any suitable solution.

I use one single MainActivity with a FragmentContainerView on it. There is one BaseFragment with a custom layout and that layout owns my Settings as child Fragment.

What did I wrong?
