Hello @Kate Taylor , Thanks for using Microsoft Q&A Platform.
Can you try resource purge/ Once a resource is purged, it is permanently deleted and cannot be restored. You will lose all data and keys associated with the resource.
Here is the documentation you can refer to: https://learn.microsoft.com/en-us/azure/ai-services/recover-purge-resources?tabs=azure-portal#purge-a-deleted-resource
I hope this helps.
Regards,
Vasavi
