Avatar not rendering - Runtime Errors with Full Body XR (Beta)

[skymeson]

Describe the bug
I'm getting runtime errors and my avatar is not rendering when using the AvatarControl scene when Full Body XR (Beta) is selected.

SkinnedMeshRenderer: Rendering stopped because the data for mesh 'SkinnedMesh_Avatar' on Game Object 'Renderer_Avatar' does not match the expected mesh data size and vertex stride.

All avatars load fine in the default samples but I'm having issues in the Netcode sample scene.

I've tried Standard and URP projects using both Unity 2021.3.44 and Unity 6.
