Maui MediaPicker.Default.CapturePhotoAsync fails under iOS with no error message

[grantsss]

Description

Hi,

When I try to capture an image on a physical Apple device using MediaPicker.Default.CapturePhotoAsync() the calling function stops functioning with no error message and returns a null.

My project is running the following packages:

I am getting the same results on a iPhone 8 running iOS 16.3.1 and a iPad Air 2 running iOS 15.8.2.

Works under Windows and Android.

Thanks for your help,

Grant

Steps to Reproduce

When I try to capture an image on a physical Apple device using MediaPicker.Default.CapturePhotoAsync() the calling function stops functioning with no error message and returns a null.

Code sample:

    public async Task<List<Photo>> TakePic(ContentPage page)
    {
        var Photos = new List<Photo>();

        Photo photo = new Photo();

        try
        {
            await page.DisplayAlert("Debug", $"IsCaptureSupported {MediaPicker.Default.IsCaptureSupported}", "Ok");
            if (MediaPicker.Default.IsCaptureSupported)
            {
                await page.DisplayAlert("Debug", $"taking pic", "Ok");

                var photoFile = await MediaPicker.Default.CapturePhotoAsync();


                if (photoFile != null) /iOS returns null here?

Hi @grantsss, does it works if you call the CapturePhotoAsync inside the MainThread.InvokeOnMainThreadAsync?
