I am trying to delete a Workflow from an ItemRevision, it gave me an error: The instance is being referenced. I checked the Impact Analysis and its not showing any reference.
I tried using two utilities and its not helping: verify_tasks and clear_process_stage_list

The way I understood is from impact analysis you are unable to locate the workflow ?!
If my understanding is right, then try if this helps to locate the workflow job (to remove item revision from the workflow viewer --> attachments):
Is your workflow template configured to create envelopes or any additional references?
Do let me know if I misunderstood your question?
