Black Screen after Sharing on Facebook using UIActivityViewController.

Hi I am using UIActivityViewController to share content on social networks but facing one issue. The issue is when i select the share button the UIActivityViewController gets appear and I select the Facebook option.

I select the Facebook option in the sharing sheet -> Facebook sharing view appears with two options (Cancel and Next). When I select the Cancel button giving me another action sheet to discard or keep the post. When i select to discard the Action Sheet get disappear but the Facebook sharing view still keep showing and there is no way to go back.

Second when I press the next button in the Facebook sharing view -> another Facebook view gets appear with two buttons (Cancel and Share).... When I click the share button content get share on Facebook and black screen appears with a check in circle and text "Shared to Facebook!" .. And the application get stuck on this Screen.

Below is my code, Any help would be appreciated, I am also using the activityViewController!.completionWithItemsHandler but this closure not getting called in case of Facebook.

  let url = "\(UserDefaults.baseURL)/pl/\(resource)/\(sharingId)"
// set up activity view controller
let imageToShare = [ url ]
activityViewController = UIActivityViewController(activityItems: imageToShare, applicationActivities: nil)


activityViewController!.popoverPresentationController?.sourceView = self.view // so that iPads won't crash
// exclude some activity types from the list (optional)
activityViewController!.excludedActivityTypes = [UIActivity.ActivityType.airDrop]

activityViewController!.completionWithItemsHandler = { (activityType: UIActivity.ActivityType?, completed:
Bool, arrayReturnedItems: [Any]?, error: Error?) in
    
    
    if completed {
        print("share completed")
        self.dismiss(animated: true)
        return
    } else {
        print("cancel")
        self.dismiss(animated: true)
    }
    if let shareError = error {
        print("error while sharing: \(shareError.localizedDescription)")
    }
}

// present the view controller
self.present(activityViewController!, animated: true, completion: nil)
