java - Kotlin 协程重复调用 Log.e 语句并在 ViewmodelScope 中崩溃应用程序

Question

我正在尝试制作一个应用程序，我可以在其中访问设备上的文件夹并收集数据，并且该应用程序在大多数设备上都可以正常运行，但是在某些设备上，当我尝试通过在所有函数中记录语句以查看执行进行调试时，它无法正常工作代码然后我发现在协程中一切似乎都很好，但是突然重复触发了一个 Log 语句，然后应用程序抛出了一些错误并崩溃了应用程序

try {
                viewModelScope.launch(Dispatchers.Default) {
                    Log.e("Debug", "Coroutine started")
                    val root = File(StickerContentProvider.FILES_LOCATION)
                    val state = Environment.getExternalStorageState()
                    if (Environment.MEDIA_MOUNTED == state || Environment.MEDIA_MOUNTED_READ_ONLY == state) {
                        var count: Int = 0
                        root.walkBottomUp().forEach {
    
                            if (it.name.endsWith(".webp"))
                            {
                                val webp : WebPImage = WebPImage.createFromByteArray(it.readBytes())
                                if(animated && webp.frameCount > 1 && webp.height == 512 &&  webp.width == 512 )
                                {
                                    fileList.add(it)
                                    Log.e("Debug", it.name + " added")
                                }
                                else
                                if(!animated && webp.frameCount <= 1)
                                {
                                    fileList.add(it)
                                    Log.e("Debug", it.name + " added")
    
                                }
    
                            }
                        }
                        fileList.sortWith(Comparator.comparingLong(File::lastModified).reversed())
                        Log.e("Debug", "adding sorted items ")
                        while(count != 100) {
                            list.add(Items( BitmapFactory.decodeFile(fileList[count].path),fileList[count].name, Uri.fromFile(fileList[count]),fileList[count].absoluteFile.totalSpace.toString()))
                            count++
                        }
                        Images.postValue(list)
                    }
                }
            }
            catch (e:Exception)
            {
                Log.e("Exception", e.message!! )
            } 

此代码运行良好，但在某些设备中，其崩溃日志如下
