Cannot delete invisible Log Analytics Workspace

It does happen whenever resource deletion was not performed correctly. for example, where resources were still being provisioned if we issued delete operations or order of deletion was not performed correctly. see by waiting for a day if it cleans up by itself if not create support ticket to Microsoft.

It happens with me as well, NIC is attached to VM which was already deleted whenever I try to delete NIC , it gives error it already been used. only solution for this kind of issue to raise issue with Microsoft .
