I cannot delete resource group <resource-group>. Its only remaining resource is:

Microsoft.AzureActiveDirectory/ciamDirectories/name1dom1.onmicrosoft.com

The resource has provisioningState: Failed.
Deletion returns 403 Forbidden: Only Global Administrators for this directory can manage its settings. An earlier attempt returned AADB2C95060: UserCountExceeded.
The associated external tenant is different from my main tenant. I believe it was created earlier and then I deleted the account maybe an entra account and I no longer remember which one it was.

I cannot complete the normal tenant-deletion prerequisites because the directory is inaccessible.
