Plugin.Media Not Working on Prism Xamarin Forms (TakePhotoAsync) - visual-studio

Question

I know this question is not new, but I am really stuck on this for days, and I need your support.
My problem is:
I can't take pictures in my prism xamarin forms project using the plugin media for Android (it works for selecting images from gallery though).
The Error I get is:
unable to get file location xam plugin media site
I would love to hear from you guys, and thanks in advance for your support.
Here i my code:
