Resolution Note:
Older iOS devices appear to be too old to be able to run either of these compute shaders.
A potential workaround for Barracuda shaders is to use the Pixel Shader Barracuda worker. Make sure to use 2.3.0 or later Barracuda version:
WorkerFactory.CreateWorker(WorkerFactory.Type.PixelShader, model)
