Model deployment blocked by error 715-123420 (Real-Time Fraud Protection)

Summary:

Anthropic Claude model deployments on my Azure AI Foundry (AIServices) resource are being blocked at the platform level with error 715-123420 ("An error occurred. Please reach out to support for additional assistance."). This code corresponds to a Real-Time Fraud Protection (RTFP) hold. I am requesting that the RTFP/security team review this subscription and lift the deployment block so model deployments can proceed.

This is NOT a configuration, quota, region, or permissions issue — I have already ruled those out:

• I am Owner on the subscription and Global Administrator on the tenant.
• Quota for the target model is approved and visible.
• The model (claude-sonnet-4-6) is confirmed available in East US 2 via "az cognitiveservices model list".
• I cleared the earlier InvalidModelProviderData error by submitting the required modelProviderData fields (organizationName, countryCode, industry) via the ARM REST API (api-version 2025-10-01-preview). The request now fails immediately with 715-123420, before model provisioning begins.
• The deployment fails identically via both REST/CLI and the portal, confirming it is platform-side, not a UI or template issue.

I have the same issue for text-embedding-large and gpt-chat-latest as well
