My packaged game does not have my nav mesh active or my widget materials

So I recently tried packaging and uploading my second game to itch.io. However, upon packaging it and playing it I realized that the characters moving to different points on nav meshes do not actually move anymore. This has lead me to believe that the nav meshes are not packaged. Also, for the HUD widget I have icons that I used a blueprint, material, and render target to capture a 2D picture of the object and display it to my widget. However, every time I close and reopen the project or packaged game it doesn’t show the icons because in the blueprint it default views to the event graph rather than the viewport of the blueprint. Blueprint SceneCaptureComponent2D camera is not capturing the 3d object unless I tab look at the viewport of the BP. It shows nothing in my Texture Target.
