anthos-samples /anthos-bm-gcp-terraform failing cluster deployment

I'm following the instructions [here](https://github.com/GoogleCloudPlatform/anthos-samples/blob/main/anthos-bm-gcp-terraform/docs/quickstart.md) and [here](https://github.com/GoogleCloudPlatform/anthos-samples/blob/main/anthos-bm-gcp-terraform/docs/quickstart.md), both for manual and all-in-one-install of a bare metal cluster using vxlan on GCE.

Both installation attempts fail at the Deleting bootstrap cluster step in the abm cluster installation from the admin workstation with the error:

```text
[2025-09-11 17:57:37+0000] Installing dependency components... OK
[2025-09-11 17:59:18+0000] Deleting bootstrap cluster... OK
[2025-09-11 17:59:21+0000] exit with error
[2025-09-11 17:59:21+0000] Error creating cluster: 1 error occurred:
* API cloudresourcemanager.googleapis.com is not enabled in project [REDACTED]
```

This error can also be seen in the `create-cluster.log` file:

```

However, the API is enabled in the project:

```bash
gcloud services list --enabled | grep -i cloudresourcemanager
cloudresourcemanager.googleapis.com Cloud Resource Manager API
```
