接受呼叫后使用openTok（CallKit）-UsingopenTokafteracceptaCall(CallKit)

I am working on a project which requires opentok and callkit for notifying users. However, the application keeps crashing when openTok tries to connect to a session. IDK what is going on right now. Here is my work flow and codes:

我正在开发一个需要opentok和callkit来通知用户的项目。但是，当openTok尝试连接到会话时，应用程序会一直崩溃。 IDK现在正在发生什么。这是我的工作流程和代码：

Push notification about available opentok session -> start incoming call -> user accept the call -> start the opentok storyboard -> do some backend stuff -> connect to a session !!!! THIS IS WHEN IT CRASHES.

推送关于可用的opentok会话的通知 - >开始传入呼叫 - >用户接受呼叫 - >启动opentok故事板 - >做一些后端的东西 - >连接到会话!!!!这就是它崩溃的时候。

ERROR: Thread 1: EXC_BAD_ACCESS (code=2, address=0x1968a0ad8)

错误：线程1：EXC_BAD_ACCESS（代码= 2，地址= 0x1968a0ad8）

Besides, I would like to ask for advice about receive notification. Instead of showing the notification on the screen. I would like to start the call, using callkit, like whatsapp or fb messenger. Please give me a hint about this also. Right now, I can only start the call when the app is in foreground when push notification is sent.

此外，我想询问有关接收通知的建议。而不是在屏幕上显示通知。我想使用callkit开始调用，比如whatsapp或fb messenger。请给我一个暗示。现在，我只能在发送推送通知时应用程序处于前台时启动呼叫。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification
    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)
    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)

    let aps = userInfo["aps"] as! [String: AnyObject]
    // 1
    if aps["content-available"] as? Int == 1 {

        let uuid = UUID(uuidString: MyVariables.uuid)
        AppDelegate.shared.displayIncomingCall(uuid: uuid!, handle: "Sanoste", hasVideo: false) { _ in
        }
    }else  {
        return
    }

    completionHandler(UIBackgroundFetchResult.newData)
}


func provider(_ provider: CXProvider, perform action: CXAnswerCallAction) {

    action.fulfill()
    AppDelegate.shared.openTok()
}


func openTok() {

    let mainStoryboard = UIStoryboard(name: "callView", bundle: nil)
    let vc = mainStoryboard.instantiateViewController(withIdentifier: "callViewController") as! callViewController

    vc.view.frame = UIScreen.main.bounds
    UIView.transition(with: self.window!, duration: 0.5, options: .transitionCrossDissolve, animations: {
        self.window!.rootViewCOntroller= vc
    }, completion: nil)

}

// Join a session from MBE
func joinSession() {

    var error: OTError?

    pSession = OTSession(apiKey: openTokSessionKey.pApiKey, sessionId: openTokSessionKey.pSessionId, delegate: self as OTSessionDelegate)
    pSession?.connect(withToken: openTokSessionKey.pToken, error: &error)
    if error != nil {
        print(error!)
    }

    sSession = OTSession(apiKey: openTokSessionKey.sApiKey, sessionId: openTokSessionKey.sSessionId, delegate: self as OTSessionDelegate)
    sSession?.connect(withToken: openTokSessionKey.sToken, error: &error)
    if error != nil {
        print(error!)
    }
}

Anyone helps please ?
