png file image targets do not work at runtime for Unity Editor Play Mode

Vuforia SDK Version: 9.7.4 - Description with steps to reproduce: I followed the steps as described here: https://library.vuforia.com/articles/Solution/how-to-create-and-load-targets-in-unity.html I used this plugin to load images from file: https://github.com/yasirkula/UnityNativeGallery Specifically, I used < NativeGallery.GetImageFromGallery( MediaPickCallback callback, string title = "", string mime = "image/*" ): prompts the user to select an image from Gallery/Photos. /> to load the images via scripts. When trying to load images from my computer while in Play mode, I realized that only .jpg images would successfully track. Files of .png would compile without error, but would never successfully be detected. - Development OS (Mac OS X, Windows, Linux): Windows - Mobile OS and Version: Android 9 - Mobile Device Manufacturer and Model name: Google Pixel 2 (Computer is Dell Laptop Inspiron 15 5567) - Do the Vuforia Sample Applications show the same behavior?: No
