Does it support caching?

I implemented a small caching mechanism. My code loads json and displays Lottie animations on a collection view. But when I am going back (up) it crashes.

`private let cacheKey = "StickerCache"

func cache(image: UIImage?, for urlString: String) {
    let path = NSTemporaryDirectory().appending(UUID().uuidString)
    let url = URL(fileURLWithPath: path)
    
    if let imageData = image?.sd_imageData() {
        try? imageData.write(to: url)
        var dict = UserDefaults.standard.object(forKey: cacheKey) as? [String: String] ?? [String: String]()
        dict[urlString] = path
        UserDefaults.standard.setValue(dict, forKey: cacheKey)
    }
}

func loadCache(urlString: String) -> UIImage? {
    if let dict = UserDefaults.standard.object(forKey: cacheKey) as? [String: String] {
        if let path = dict[urlString] {
            if let data = try? Data(contentsOf: URL(fileURLWithPath: path)) {
                let scale = UIScreen.main.scale
                let option = [SDImageCoderOption.decodeThumbnailPixelSize: CGSize(width: 80 * scale,
                                                                                  height: 80 * scale)]
                // Crashes here
                return SDImageLottieCoder.shared.decodedImage(with: data, options: option)
            }
        }
    }
    
    return nil
}

`
It does not output anything to the console, but I guess it has something to do with json decoding. maybe you can steer me into the right direction.
