### Current Behavior

When I have a CameraView and start a Preview so a Picture can be captured the System.InvalidOperationException: Unable to retrieve Handler is raised.

Occurs on both iOS and Android.

`{System.InvalidOperationException: Unable to retrieve Handler at CommunityToolkit.Maui.Views.CameraView.get_Handler() in /_/src/CommunityToolkit.Maui.Camera/Views/CameraView.shared.cs:line 195 at CommunityToolkit.Maui.Views.CameraView.StartCameraPreview(CancellationToken token) in /_/src/CommunityToolkit.Maui.Camera/Views/CameraView.shared.cs:line 255 at MauiAppCameraView.Pages.CameraViewPage.OnAppearing() in D:\repo\MauiAppCameraView\MauiAppCameraView\Pages\CameraViewPage.xaml.cs:line 18 at System.Threading.Tasks.Task.<>c.b__128_0(Object state) at Foundation.NSAsyncSynchronizationContextDispatcher.Apply() in /Users/builder/azdo/_work/2/s/macios/src/Foundation/NSAction.cs:line 179 at Foundation.NSAsyncSynchronizationContextDispatcher.__Registrar_Callbacks__.callback_3681_Foundation_NSAsyncSynchronizationContextDispatcher_Apply(IntPtr pobj, IntPtr sel, IntPtr* exception_gchandle)}`

### Expected Behavior

CameaView works as documented. start a Preview and then capture an image.

### Steps To Reproduce

1. Open and debug simple app from repo at [https://github.com/Chris-Marassovich/MauiAppCameraView](url)
2. From the Shell Menu choose the "Camera" menu option and you should see the exception.

### Anything else?

Temporary workaround

Falling back to MediaPicker.CapturePhotoAsync() resolves the issue, but this is not suitable for us as I need to default the flash to off. This is a critical point for us and the only way I can programmatically default the flash to off is to use the CameraView.

If I can use the MediaPicker and still be able to default the flash to off that would be extremely helpful.
