Getting FileNotFoundException when trying MediaFile.OpenReadAsync() on Android

[McFlemchSoda]

Hi,

I'm having an issue when using using var file = await MediaGallery.CapturePhotoAsync(); en then wanting to open a stream on the photo just captured on Android. iOS works as expected.
I have the following code:

using var file = await MediaGallery.CapturePhotoAsync();
var newFile = Path.Combine(FolderPath, file.NameWithoutExtension);
using (var stream = await file.OpenReadAsync())
{
    using (var newStream = File.OpenWrite(newFile))
    {
        await stream.CopyToAsync(newStream);
        await stream.FlushAsync();
        await newStream.FlushAsync();
    }
}

On this line using (var stream = await file.OpenReadAsync()) I will get the FileNotFoundException. Stacktrace posted below.

I've triple checked all my manifest records and the OnActivityResult in the MainActivity. I've followed the readme for android and I do get to take a picture, but it just can't read the file. File is not null and I can see the tempPath and uri.
Picking a picture does work, and I use the same code as above to save the chosen picture. That might be because they're saved in different directories?

I thought it might be a bug but when I made a sample project with the exact same code shown above, it does work correctly. So it must be some weird effect in my own project and I was wondering if you might have any idea what could be causing this exception. Like, why would my app not be able to find the cache directory (if that's where it's supposed to be)?

Edit:
I checked all permission regarding camera, read/write storage and external storage. Everything is granted.
After taking a picture I get the MediaFile, but if I check the cache directory right after, it could not find the directory XamarinMediaGalleryCacheDir.
So Directory.Exists(cachePath + "/XamarinMediaGalleryCacheDir") does not exist right after taking a photo. I got this path from the tempFilePath you get in the MediaFile. So this would explain the FileNotFoundException, but why would the directory not be created after taking the picture? Same goes with File.Exists(tempFilePath), all is false right after taking the picture.

Would love to hear from you.

@McFlemchSoda Hi. I'm sorry. I haven't seen this discussion.
Maybe have you found a solution yet?
