MediaPicker.CapturePhotoAsync() fails with UnauthorisedAccessException on IOS despite successfully being Granted Access

[mwilson25]

Description

Not sure if I missed the memo and I need to do something else to make this work?

I have just upgraded one of my IOS MAUI app to .Net 10. I now find my users are blocked from accessing the Camera via the App despite being asked to grant permission and then granting that permission. Checking the IOS device Settings Page indicates Permission for the Camera has been granted

Here is my Code

async void OnCapturePhotoClicked(object sender, EventArgs e)
{
    try
    {
        FileResult file = await MediaPicker.CapturePhotoAsync();
        if (file != null)
        {
            await AddJobImageAttachment(file);
        }
    }
    catch (UnauthorizedAccessException)
    {
        await DisplayAlertAsync("Camera Access", "Camera access is not currently allowed", "OK");
    }
}

In the plist file I have

NSCameraUsageDescription
Job Image Camera
NSPhotoLibraryUsageDescription
Job Image Photo Library

Also happens on the Simulator for iPhone 16 IOS 18.4

My 9.0.10 version of one of my similar apps still works.

Steps to Reproduce

1. Create a new MAUi App
2. Add the Plist enties above for the IOS entries
3. Add a button and Add my above code
4. Run the Simulator
5. Press the button
6. Agree to permission
7. Fails with UnauthorisedAccessException

as far as I know, there isn't camera access in simulators so I wouldn't expect that to ever work on a simulator. if the bug validation was done against a simulator, it probably isn't of much value.

That's not quite right in regard the simulator. You cant take a photo on the simulator camera . But the Camera app does appear to come up (showing some camera controls on a grey background). What you do not get is an unauthorisedaccess exception. Which is my issue.
