There is a solution mentioned in the comments that seems to be working for me. Make your FragmentStateAdapter user the constructor

From your container fragment create the adapter as follows:

FragmentManager fm = getChildFragmentManager();
Lifecycle lifecycle = getViewLifecycleOwner().getLifecycle();
fragmentAdapter = new FragmentAdapter(fm, lifecycle);
