Research direction

Reproduce the crash by entering and exiting play mode in the RenderModelSample scene, then inspect the provided managed stack trace around ValveRenderModelFeature:GetRenderModelStates and RenderModelLoader:UpdateAnimations. Done means exiting play mode no longer causes Unity's native crash; collect detailed logs or crash dumps if the failure persists.
