Answer 1

Basically, you are using the wrong approach or the wrong way to sending data from one fragment to another. You are using ViewPager with TabLayout so every tab item has its own fragment and you are calling the second tab item's fragment in the first tab item. That's not correct!

Use ViewModel for sending data between two fragments. Your issue will be resolve. See the documentation.

Answer 2

Try to update getChildFragmentManager in place of getSupportFragmentManager inside Fragment

or just try the below way inside mainActivity and call from where you want

public void changeFragmentFrom(Fragment targetFragment, byte state) {
        try {
            if (defaultState == state)
                return;
            
            FragmentTransaction ft = getSupportFragmentManager()
                    .beginTransaction();
            ft.replace(R.id.main_layout, targetFragment, "" + state);
            ft.addToBackStack("" + state);
            defaultState = state;
            ft.commit();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Please try to implement this way if your requirement match in given link
