the camera remains switched on during use, if you try to use the camera again, it is unavailable

The code is in try catch, nothing is written to the unity app logs. It's possible read log of hololens?where is the file location?

var mediaCapture = new MediaCapture();             
await mediaCapture.InitializeAsync(_captureInitSettings);             
var lowLagCapture = await mediaCapture.PrepareLowLagPhotoCaptureAsync(ImageEncodingProperties.CreateUncompressed(MediaPixelFormat.Bgra8));             
var capturedPhoto = await lowLagCapture.CaptureAsync();             
var softwareBitmap = capturedPhoto.Frame.SoftwareBitmap;             
await lowLagCapture.FinishAsync();             
mediaCapture.Dispose();
