java.lang.AbstractMethodError

[AlexFlexer]

Code snippet from my fragment where my app crashes:

class SplashChooseFragment : Fragment(R.layout.fr_splash_choose) {
    private val mBind  by viewBinding(FrSplashChooseBinding::bind)

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        mBind.btnLogin.setOnClickListener {
            findNavController().navigate(R.id.action_fr_splash_choose_to_nav_login)
        }
        mBind.btnRegister.setOnClickListener {
            findNavController().navigate(R.id.action_fr_splash_choose_to_nav_register)
        }
    }
}

But when I create fragment's view like this, everything works just fine, no crashes:

class SplashChooseFragment : Fragment() {
    //private val mBind  by viewBinding(FrSplashChooseBinding::bind)
    private var _binding: FrSplashChooseBinding? = null
    val mBind: FrSplashChooseBinding
        get() = _binding!!

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        _binding = FrSplashChooseBinding.inflate(inflater, container, false)
        return mBind.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        mBind.btnLogin.onClick {
            findNavController().navigate(R.id.action_fr_splash_choose_to_nav_login)
        }
        mBind.btnRegister.onClick {
            findNavController().navigate(R.id.action_fr_splash_choose_to_nav_register)
        }
    }
}

I use 1.4.7 version of the library
