crash when preview a video asset

[bingbingBang]

When I use FMPhotoPicker select video asset, this method func requestAVAsset(asset: PHAsset, complete: @escaping (AVAsset?) -> Void) always return a nil asset and the player won't be initialized, tap play button and nothing happends , a fews seconds later the app crash because some UI modifications performed from a background thread, I try to fix first problem by adding an option to PHImageManager and it works:

            let manager = PHImageManager.default()
            let option = PHVideoRequestOptions()
            option.isNetworkAccessAllowed = true
            
            manager.requestAVAsset(forVideo: asset, options: option) { asset, audioMix, _ in
                DispatchQueue.main.async {
                    complete(asset)
                }
            }

hope help, and the other problem I took a screenshot for your reference，hope useful：
