Azure Machine Learning: Deletion of orphaned registry resources — Assistance Needed

Problem description

I am seeking assistance with deleting leftover resources related to an Azure Machine Learning registry that remained after deleting the associated managed application and resource group. The resources are considered orphaned, and previous attempts to delete them have failed, with errors indicating permission issues and deny assignments.

Environment

Azure Machine Learning, registry in a resource group in the West Europe region.

What I've already tried

I have already deleted the parent managed application and the associated managed resource group. Despite this, the registry and related resources remain, and I have attempted deletion commands via Azure CLI, which resulted in permission errors due to deny assignments. I have also verified that there are no resource locks in place.

Current status

I am looking for guidance on how to proceed with removing these orphaned resources, including any steps to resolve permission issues or how to escalate the cleanup to the engineering team if necessary.
