Application stops after swiping

I have an app reader like Apple Books. And I have a problem. I have NavigationViewController next FirstViewController with book button, SecondViewController it is a reader and TableViewController it is settings for text size. But if I open book in FirstViewController go to SecondViewController and in navigation bar tab aA button and open TableViewController all works fine. But after if I want back to FirstViewController I not close TableViewController and do swipe from left to right my app stops. How to fix it?

SecondViewController:

@IBOutlet weak var textSettings: UIButton!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        setupGestures()
    }
    
    // MARK: - Text Settings View
    
    private func setupGestures() {
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(tapped))
        tapGesture.numberOfTapsRequired = 1
        textSettings.addGestureRecognizer(tapGesture)
    }
    
    @objc private func tapped(){
        guard let popVC = storyboard?.instantiateViewController(withIdentifier: "popVC") else { return }
        popVC.modalPresentationStyle = .popover
        let popOverVC = popVC.popoverPresentationController
        popOverVC?.delegate = self
        popOverVC?.sourceView = self.textSettings
        popOverVC?.sourceRect = CGRect(x: self.textSettings.bounds.midX, y: self.textSettings.bounds.maxY, width: 0, height: 0)
        popVC.preferredContentSize = CGSize(width: 250, height: 250)
        
        self.present(popVC, animated: true)
    }
}

extension SecondViewController: UIPopoverPresentationControllerDelegate {
    
    func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
        return .none
    }
}

Other controllers have no special code. Video illustrating the problem - https://drive.google.com/file/d/1HUV26H4VFoKglh8FbkNP0y2Y3rYl4Q_f/view?usp=sharing
