Null reference exceptions in play mode when Experimental Play Mode options are enabled.

Seems like the gesture manager only works once successfully. After leaving playmode once and going back in I’m spammed with null reference exceptions.

MissingReferenceException: The object of type 'AnimationClip' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Looking into it, it seems that the ModuleVrc3Styles.Data.GestureClips array is full of null AnimationClips and the code is trying to grab the name of them.

Nothing unusual about my setup, I’d think. I only have 1 scene loaded with one avatar. Just looks like unity is destroying the animation clips.

Using VRCSDK3-AVATAR-2022.06.03.00.04 and Unity 2019.4.31f.
