Crash: Thread 2: "-[NSTaggedPointerString count]: unrecognized selector sent to instance 0xaa672ff3b4678003"

Hello Everyone, I'm still a beginner and don't have that much experience with Swift. I keep getting this error when I want to start my app "Thread 2: "-[NSTaggedPointerString count]: unrecognized selector sent to instance 0xaa672ff3b4678003"" . What can I do about it Please help.

Here is my AppDelegate :

import UIKit

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func updateLocalizedTexts() {
        // Überprüfen der Spracheinstellung der App und Erstellen des entsprechenden String-Bundles
        let currentLanguage = Locale.current.languageCode
        guard let path = Bundle.main.path(forResource: currentLanguage, ofType: "lproj"),
            let bundle = Bundle(path: path) else {
            return
        }
        
        // Alle Labels in der App abrufen
        guard let window = self.window else {
            return
        }
        let allLabels = getAllLabelsInViewHierarchy(view: window)
        
        // Aktualisieren der lokalisierten Texte für alle Labels
        for label in allLabels {
            if let labelText = label.text {
                label.text = NSLocalizedString(labelText, tableName: nil, bundle: bundle, value: "", comment: "")
            }
        }
    }

    func getAllLabelsInViewHierarchy(view: UIView) -> [UILabel] {
        var labels: [UILabel] = []
        
        // Alle Views in der Ansichtshierarchie abrufen
        let allViews = getAllViewsInViewHierarchy(view: view)
        
        // Filtere die Views nach UILabels und füge sie zur Ergebnisliste hinzu
        for view in allViews {
            if let label = view as? UILabel {
                labels.append(label)
            }
        }
        
        return labels
    }
    
    func getAllViewsInViewHierarchy(view: UIView) -> [UIView] {
        var views: [UIView] = []
        
        // Füge die übergebene View zur Ergebnisliste hinzu
        views.append(view)
        
        // Durchlaufe alle Unterviews der übergebenen View (rekursiv)
        for subview in view.subviews {
            views += getAllViewsInViewHierarchy(view: subview)
        }
        
        return views
    }

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        updateLocalizedTexts()
        
        return true
    }

    // MARK: UISceneSession Lifecycle

    func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
        // Called when a new scene session is being created.
        // Use this method to select a configuration to create the new scene with.
        return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
    }

    func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
        // Called when the user discards a scene session.
        // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
        // Use this method to release any resources that were specific to the discarded scenes, as they will not return.
    }

    func application(_ application: UIApplication, didChangeStatusBarFrame oldStatusBarFrame: CGRect) {
        updateLocalizedTexts()
    }
