Xamarin ios ZXING scanner not analyzing QR - ios

Question

i'm using an Iphone 10 with ios 15.3.1,Zxing version = 2.4.1, compiling the xamarin project in windows. I been trying to make a qr scanner with zxing for ios android, but when i run my app in ios, it won't go to the onResult event. I've tried with a lot of methods of doing this, but nothing seems to work. The camera shows, but the result never comes truh. ¿Does someone have any idea why this is happening? I also tried apps from other devs that are using zxing and it also dosen't work. but when i scan with the camera app it works.
async void OnButtonClickedAsync(object sender, System.EventArgs e)
{
var options = new ZXing.Mobile.MobileBarcodeScanningOptions
{
CameraResolutionSelector = HandleCameraResolutionSelectorDelegate
};
MobileBarcodeScanner scanner = new MobileBarcodeScanner();
//scanner.TopText = "Hold camera up to barcode to scan";
//scanner.BottomText = "Barcode will automatically scan";
//scanner.UseCustomOverlay = false;
scanner.FlashButtonText = "Flash";
scanner.CancelButtonText = "Cancel";
scanner.Torch(true);
scanner.AutoFocus();
var result = await scanner.Scan(options);
HandleScanResult(result);
}
void HandleScanResult(ZXing.Result result)
{
if (result != null && !string.IsNullOrEmpty(result.Text))
scanResultText.Text = result.Text;
}
CameraResolution HandleCameraResolutionSelectorDelegate(List<CameraResolution> availableResolutions)
{
//Don't know if this will ever be null or empty
if (availableResolutions == null || availableResolutions.Count < 1)
return new CameraResolution() { Width = 800, Height = 600 };
//Debugging revealed that the last element in the list
//expresses the highest resolution. This could probably be more thorough.
return availableResolutions[availableResolutions.Count - 1];
}

I compiled using a mac and it worked fine, must be a bug of visual studio on windows.
