iOS 当我从 iOS 设置屏幕更改文本大小时，App UILabel 崩溃

Question

I have

@IBOutlet weak var onlineStatusLabel: UILabel! 

declared in TableViewCell Class My table view use static cells. When I inside the app everything is ok, once I change text size setting in iOS setting screen and come back to my app, app crashes with this error:

appName/TableVC.swift:47: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

This is what I call from my TableVC:

import UIKit

class TableVC: UITableViewController {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }
    
    override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
      //  super.tableView(tableView, willDisplay: cell, forRowAt: indexPath)
        guard let cell = cell as? CustomTableViewCell else { return }
        cell.onlineStatusLabel.textColor = .red // app crash here, this means that onlineStatusLabel is nil, but how???
        cell.onlineStatusLabel.text = "Text"
    }
}

CellView:

import UIKit

class CustomTableViewCell: UITableViewCell {
    @IBOutlet weak var onlineStatusLabel: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

}

How it can be nil? How size change can react on UILabel? Can you please suggest?
