This works as designed. The NonDeterministicWorkflowPolicy is associated to a specific workflow type. As you are starting workflow with a different type the worker rejects the workflow it doesn't support. As it is usually an intermittent problem in production (for example during rolling deployment of the new workflow code) the workflow is not terminated, but is blocked.
