I am encountering an issue with the UICollectionView where the screen sometimes turns black, or the video occasionally gets stuck. Could you please assist me in resolving this?

Here is my code `class FeedViewController: UIViewController {

@IBOutlet weak var collectionView: UICollectionView!

var items: [URL] = [
    URL(string: "https://bk1.goomooz.net/dev/public/storage/post/itamimage/r43trITADsWpFztxESeYW9ZPSP7LWMzSjKForScq.mov")!,

]

override func viewDidLoad() {
    super.viewDidLoad()
    collectionView.dataSource = self
    collectionView.delegate = self

    collectionView.register(UINib(nibName: "FeedCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "FeedCollectionViewCell")
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    check()
}

deinit {
    print("Call deinit")
}

}

extension FeedViewController: UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout{

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    items.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "FeedCollectionViewCell", for: indexPath) as! FeedCollectionViewCell
    cell.set(url: items[indexPath.row])
    return cell
}

func check() {
    checkPreload()
    checkPlay()
}

func checkPreload() {

    guard let lastRow = collectionView.indexPathsForVisibleItems.last?.item else { return }

    let urls = items
        .suffix(from: min(lastRow + 1, items.count))
        .prefix(2)

    VideoPreloadManager.shared.set(waiting: Array(urls))
}

func checkPlay() {
    let visibleCells = collectionView.visibleCells.compactMap { $0 as? FeedCollectionViewCell }

    guard visibleCells.count > 0 else { return }

    let visibleFrame = CGRect(x: collectionView.contentOffset.x, y: 0, width: collectionView.bounds.width, height: collectionView.bounds.height)
