[iOS] Media Picker UIImagePickerController closing issue

[amahera]

Description

If we use await MediaPicker.Default.PickPhotoAsync() and then try to open alert - await DisplayAlert(result?.FileName, "message", "ok") -alert won't be displayed.

I believe that this is an issue with setting the result of image picking before closing UIImagePickerController.

Steps to Reproduce

1. Call and await MediaPicker.Default.PickPhotoAsync()
2. Try to open alert await DisplayAlert(result?.FileName, "message", "ok")
3. Verify that the alert is not shown

Can repro this issue at iOS platform on the latest 17.10 Preview 5(8.0.21 & 8.0.20 & 8.0.14).

Same issue here, can be worked arround by adding task.delay for 750ms. Would be nice if this would get fixed as the 750ms is just a guess and works right now, maybe this breaks on older devices as they take more time to close the dialog

running into similar issues, where trying to use the media picker (which doesn't work) will then permanently block display alerts from being displayed, rendering a good portion of the app inoperable.
running maui 9.0.10
