Can not delete aci network profile

I believe this issue occurs because the network profile you are trying to delete is still referencing an orphaned container NIC that Azure believes is in use, even though the actual container group no longer exists. To resolve this, first inspect the resource using az resource show --ids <networkProfileID> to identify the NICs linked to the profile. If you find orphaned NICs, delete them manually with az resource delete --ids <containerNicResourceId>, and then retry deleting the network profile. If the CLI still fails, use the Azure restAPI with a direct DELETE request to the network profile endpoint. In cases where the error is caused by a cross-subscription reference, verify if the NIC resource truly exists using az resource show; if it returns ResourceNotFound, it is safe to force-delete the profile. If none of these methods work, raise a support request. To prevent this in the future, always delete the container instances first before removing the network profile, and avoid creating cross-subscription dependencies without proper lifecycle management.
