Navigation Bar Large Title - Animation Issue

Question

I'm using the large title on the navigation bar, and when I tap on a cell to go on the next controller, the large title has a strange animation (as you can see on the gif below). It's doesn't disappear immediately.

I tried the following solution but nothing (https://www.morningswiftui.com/blog/fix-large-title-animation-on-ios13)

My Code:

On the first View Controller:

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        navigationItem.title = "New Order"
        navigationController?.navigationBar.prefersLargeTitles = true
}

On the Second View Controller (With the large title):

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)

        navigationItem.title = "Menu"
        self.navigationController?.navigationBar.prefersLargeTitles = false
}

Edit:

Fabio's answer is the solution but now I have another problem:

When I tap on a cell a part of the navigation bar is black (as you can see below)

Answer 1

for second issue: in SceneDelegate: var window: UIWindow? in the function scene put this line:

window?.backgroundColor = .yourColor

like this:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
    // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
    // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
    guard let _ = (scene as? UIWindowScene) else { return }
    window?.backgroundColor = .white
}

set the color you want and that's it :)
