I am trying to use MVVM with Room DB in my android app but getting this exception on the splashActivity.
It was working fine until i added viewmodel and observers

class SplashActivity : AppCompatActivity() {

    private lateinit var mBinding: ActivitySplashBinding
    private lateinit var authVM: AuthViewmodel

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        mBinding = ActivitySplashBinding.inflate(layoutInflater)
        setContentView(mBinding.root)

        authVM = ViewModelProvider(this)[AuthViewmodel::class.java]

        observeLoginStatus()
    }

    private fun observeLoginStatus() {
        authVM.getUserLoginStatus?.observe(this, Observer { loggedInUser ->
            if (loggedInUser != null) {
                Handler().postDelayed({
                    navigateToMainActivity()
                }, 3000)
            } else {
                Handler().postDelayed({
                    navigateToAuthActivity()
                }, 3000)
            }
        })
    }

    private fun navigateToMainActivity() {
        val intent = Intent(this@SplashActivity, MainActivity::class.java)
        startActivity(intent)
        finish()
    }

    private fun navigateToAuthActivity() {
        val intent = Intent(this@SplashActivity, AuthActivity::class.java)
        startActivity(intent)
        finish()
    }
}
