'how can I show or present a ViewController correctly?

Whenever I show my ViewController, I get the error:

Meusic[53572:4085718] <UIView: 0x129e0bc60; frame = (0 0; 375 729); autoresize = W+H; layer = <CALayer: 0x6000005ba1c0>>'s window is not equal to <UINavigationController: 0x127011400>'s view's window!

Currently the preferencesViewcontroller doesnt have any anything. In there a reason on why this happens? I

    func preferencesButtonWasPressed() {
     
        
        print("preferencesButtonWasPressed - view didload")
        
        let root = PreferencesViewController()
        let navController = UINavigationController(rootViewController: root)
        navController.modalPresentationStyle = .fullScreen
        
        self.show(navController, sender: self)

       }

I was expected for it to show the ViewController without any error since it has worked before.

Initialise your ViewController through Storyboard initialisation first.

guard let vc = UIStoryboard(name: "PreferencesViewController", bundle: nil).instantiateViewController(withIdentifier: "PreferencesViewControllerIdentifier") as? PreferencesViewController else {
        return
    }
    self.present(vc, animated: true, completion: nil)
