Cant import models

Hello I have a very simple fbx model , without textures etc, I just wanted to import and test, but the editor always fails and gives no log on whats the problem … I tried importing in Unity and works like a charm , same thing for Unreal , but Lumberyard is so picky or has issues that doesn’t allow me to drag and drop it on the viewport!
I am about to switch engine unless you can provide me with a solution.
