Error The item X was specified more than once in the "Sources" Folder

I have a Xamarin.Forms project and I drag and drop an image into my Android resource folder, then I copied and pasted it into my UWP project, but the image is not displayed, so I changed its Build Action to Content, but The error is displayed:

Error The item "obj\Debug\MainPage.xaml.g.cs" was specified more than once in the "Sources" parameter. Duplicate items are not supported by the "Sources" parameter. XamaTask.Android

I am not sure if it is related to the images, but after duplicating, renaming and changing that property of Build Action the error started to show, I also deleted the images and changed the name several times and checked my Android.csproject but I did not find any duplicates. Edit I found the file that has the error, but once again, I can not find any duplicate, here is the code:
