            String email, pass;
            email = binding.emailBox.getText().toString();
            pass = binding.passwordBox.getText().toString();

            dialog.show();

            auth.signInWithEmailAndPassword(email, pass).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    dialog.dismiss();
                    if(task.isSuccessful()){
                        startActivity(new Intent(LoginActivity.this, MainActivity.class));
                        finish();

                    } else {
                        Toast.makeText(LoginActivity.this, task.getException().getLocalizedMessage(), Toast.LENGTH_SHORT).show();
                    }
                }
            });

        }
    });

You should make operation to check if field empty or not

if (binding.emailBox.getText().toString().isEmpty() || binding.passwordBox.getText().toString().isEmpty()) {
    // Do something, erro dialog or whatever
} else {
    login();
}

Try to check logcat and read the message
