I have a PreferenceScreen with a DialogPreference that opens a PreferenceDialogFragmentCompat when there is being clicked on. The DialogPreference has a custom dialogLayoutResource in which I set a new PreferenceFragmentCompat through xml using the <FragmentContainerView/> tag. On clicking the DialogPreference, the crash posted below occurs.

This crash does not occur when commenting out <FragmentContainerView/>

I was able to workaround this issue by using the following code in PreferenceDialogFragmentCompat:

private lateinit var mView: View

override fun onCreateDialogView(context: Context?): View {
    mView = super.onCreateDialogView(context)
    return mView
}

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?
): View? = mView

A sample project demonstrating the isue can be found [image:https://github.com/Pittvandewitt/fragmentContainerViewBugReport]
