ASP.NET MVC 5 "img" was null. Object reference not set to an instance of an object. Visual Studio 2019

ASP.NET MVC 5 Visual Studio 2019 I'm facing a problem (That Every time we have to upload file in order to create - Img Null Exception ) & Also Edit is not working (due to null exception thrown)

An exception is thrown of Img cannot be null

I don't know how to fix this null Problem , I'm beginner

Rest all is working fine In My Database I can see the file location that are saved and In my Published site I can see In Images Folder All Files are saved.
