ShaderUtilsPlugin causing error

"the trait bound `(bevy::DefaultPlugins, ShaderUtilsPlugin, PlayerPlugin, camera::CameraPlugin, WorldPlugin, bevy_third_person_camera::ThirdPersonCameraPlugin, bevy_inspector_egui::quick::WorldInspectorPlugin, bevy::prelude::MaterialPlugin<ExtendedMaterial<bevy::prelude::StandardMaterial, ExtensionTest>>): bevy_app::plugin::sealed::Plugins<_>` is not satisfied perhaps two different versions of crate `bevy_app` are being used?" is being reported whenever I add the ShaderUtilsPlugin, this maybe be my fault as I am new to bevy and rust. I'm using bevy 0.13.1. Much thanks Maebh!
