With the latest Oculus SDK in Unity 2019.4.11f I get tons of this error message. I have no clue what is causing it. It throws a lot of these and after some time it stops. On Quest 2 in this case sometimes the avatar hands are white as if the texture can't be loaded.
NullReferenceException: Object reference not set to an instance of an object.
