I have upgrade Xcode to last release on 15 december 2020. Now it freezes every minutes for 5 minutes it's unusable. Are there some solutions?

Hi I have an issue with Remote notification I use this PHP code to send notification function sendNotification($token, $messageText,$sound) { $tHost = 'gateway.sandbox.push.apple.com'; $tPort = 2195; // Provide the Certificate and Key Data. $tCert = 'cert/pushcert.pem'; // Provide the Private Key Passphrase (alternatively you can keep this secrete // and enter the key manually on the terminal -> remove relevant line from code). // Replace XXXXX with your Passphrase $tPassphrase = 'XXXXX'; // Provide the Device Identifier (Ensure that the Identifier does not have spaces in it). // Replace this token with the token of the iOS device that is to receive the notification. $tToken = $token; // The message that is to appear on the dialog. $tAlert = 'You have a LiveCode APNS Message'; // The Badge Number for the Application Icon (integer >=0). $tBadge = 8; // Audible Notification Option. // The content that is returned by the LiveCode "pushNotificationReceived" message. $tPayload = $messageText; // Create the message content that is to be sent to the device. $tBody['aps'] = array ( 'alert' => $tAlert, 'badge' => $tBadge, 'sound' => $sound, ); $tBody ['payload'] = $tPayload; // Encode the body to JSON. $tBody = json_encode ($tBody); // Create the Socket Stream. $tContext = stream_context_create (); stream_context_set_option ($tContext, 'ssl', 'local_cert', $tCert); // Remove this line if you would like to enter the Private Key Passphrase manually. stream_context_set_option ($tContext, 'ssl', 'passphrase', $tPassphrase); // Open the Connection to the APNS Server. $tSocket = stream_socket_client ('ssl://'.$tHost.':'.$tPort, $error, $errstr, 30, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $tContext); // Check if we were able to open a socket. if (!$tSocket) exit ("APNS Connection Failed: $error $errstr" . PHP_EOL); // Build the Binary Notification. $tMsg = chr (0) . chr (0) . chr (32) . pack ('H*', $tToken) . pack ('n', strlen ($tBody)) . $tBody; // Send the Notification to the Server. $tResult = fwrite ($tSocket, $tMsg, strlen ($tMsg)); if ($tResult) echo 'Delivered Message to APNS' . PHP_EOL; else echo 'Could not Deliver Message to APNS' . PHP_EOL; // Close the Connection to the Server. fclose ($tSocket); } When I execute this it returns "Delivered Message to APNS" but if I put a breakpoint inside func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) { } no notification arrives. All processes of "registerForPushNotifications" are correct. The strange thing is that everything worked until a month ago. This make me crazy. Please help me
