WKWebView layout problem when tap in a form input

I have a simple ViewController with a WKWebView, the page renders ok and there is no problem at first.

This is the code:

Code Block import UIKit
import WebKit
class SignIWkWebViewViewController: UIViewController {
 
   var wkWebView: WKWebView!
   override func loadView() {
     let webConfiguration = WKWebViewConfiguration()
     wkWebView = WKWebView(frame: .zero, configuration: webConfiguration)
     view = wkWebView
   }
 
   override func viewDidLoad() {
     super.viewDidLoad()
     startLoad()
   }
   
   // Receive Transfer Details and Results with a Delegate
   private lazy var session: URLSession = {
     let configuration = URLSessionConfiguration.default
     configuration.waitsForConnectivity = true
     return URLSession(configuration: configuration, delegate: self, delegateQueue: nil)
   }()
   
   var receivedData: Data?
   
   private func startLoad(){
     print("\(type(of: self)) \(#function)")
     
     guard let url = URL(string:"https://itunesconnect.apple.com/login") else { fatalError("Can not get url") }
     
     receivedData = Data()
     let task = session.dataTask(with: url)
     task.resume()
   }
   
   private func handleClientError(_ error: Error){
     print("Error: \(error)")
   }
}
   
extension SignIWkWebViewViewController : URLSessionDataDelegate{
 func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive response: URLResponse, completionHandler: @escaping (URLSession.ResponseDisposition) -> Void) {
    print("\(type(of: self)) \(#function)")
     guard let response = response as? HTTPURLResponse,
       (200...299).contains(response.statusCode),
       let mimeType = response.mimeType,
       mimeType == "text/html" else {
       completionHandler(.cancel)
       return
     }
     completionHandler(.allow)
   }
   func urlSession(_ session: URLSession, dataTask: URLSessionDataTask, didReceive data: Data) {
     print("\(type(of: self)) \(#function)")
     self.receivedData?.append(data)
   }
   func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) {
      print("\(type(of: self)) \(#function)")
     DispatchQueue.main.async {
       //self.loadButton.isEnabled = true
       if let error = error {
         self.handleClientError(error)
       } else if let receivedData = self.receivedData,
         let string = String(data: receivedData, encoding: .utf8) {
         self.wkWebView.loadHTMLString(string, baseURL: task.currentRequest?.url)
       }
     }
   }
}

The issue start when I tap in the form field in the web page.

I set a breakpoint for UIViewAlertForUnsatisfiableConstraints

expr -l objc++ -O -- [[UIWindow keyWindow] autolayoutTrace]

And I got this error:

Legend:
  • - is laid out with auto layout
+ - is laid out manually, but is represented in the layout engine because translatesAutoresizingMaskIntoConstraints = YES
• - layout engine host

What is wrong in the code?
