Root Controller UINavigationBar disappears after user logout with Firebase

I'm facing a slight problem with my UINavigationBar.

I have a an Initial Root View Controller (ViewController) followed by 2 View Controllers (LoginMRNViewController and LoginOTPViewController) that are used to login the user with One Time Password. I also have NavigationController used to navigate the user to his/her homepage after logging in. In the homepage, I have a (Logout) button, that logs out the user with Firebase and navigates him/her to the Initial Root View Controller (ViewController).

The UINavigationBar works like a charm, however, whenever the user logout, he is navigated to the Initial Root View Controller (ViewController) but the UINavigationBar completely disappears!

My logout function: 

@IBAction func logoutPressed(_ sender: Any) {
    do {
        try Auth.auth().signOut()

        self.performSegue(withIdentifier: "goToLoginScreen", sender: self)
        print ("User logged out")
    } catch let error {
        print ("Failed to logout with error", error)
    }
}

Here's how my Storyboard looks like.

EDIT:

I tried to put this in my Initial Root View Controller (ViewController) and the other 2 View Controllers (LoginMRNViewController and LoginOTPViewController) in the ViewWillAppear method, but unfortunately it did not work.

self.navigationController?.setNavigationBarHidden(false, animated: false)
tabBarController?.tabBar.isHidden = false

Here's how my updated Storyboard look like.

Don't add the another NavigationController to hide back button.

Add navigationItem.setHidesBackButton(true, animated: true) to hide back button.

Then on logout simply add self.navigationController?.popToRootViewController(animated: true)

It should work as expected.
