I faced the same problem. So,instead of this,

binding.signUpLink.setOnClickListener(Navigation.createNavigateOnClickListener(R.id.action_loginFragment_to_signUpFragment, null));

I used my NavHostFragment to find the NavHostFragment:

Button button = (Button)findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Fragment navhost = getSupportFragmentManager().findFragmentById(R.id.fragment2);
                NavController c = NavHostFragment.findNavController(navhost);
                c.navigate(R.id.firstFragment);


            }
        });

fragment2 is navhostfragmentID.
