Partner Center Hardware Developer Program: workspace shows "account has been deactivated", attestation signing blocked

Summary: We have been trying to resolve this single issue for more than a month, routed in circles across multiple support channels with no resolution. I'm posting here because similar Hardware-deactivation cases seem to actually reach the Partner Center / Hardware team on Q&A.

Service: Microsoft Partner Center — Windows Hardware Developer Program (driver attestation signing).

Scenario / what we're trying to do: Submit a signed driver package for attestation signing so we can ship our product. Our EV code-signing certificate is validated and our signed CAB is ready to upload.

Result / the problem: The Hardware workspace is deactivated. Opening the Hardware dashboard returns "your Partner Center account has been deactivated" and redirects to partner.microsoft.com/en-us/restrictedaccess?reason=Deactivated. We cannot reach the driver submission page at all.

Environment:

• Correlation ID: c9836371-c194-41d2-a9be-3cd47c7f26cc
• Seller ID: 94871200
• Tenant: PointofTradeCo.onmicrosoft.com
• Program: Windows Hardware Developer Program

Troubleshooting efforts so far:

• Completed and submitted the enrollment questionnaire in late June; the tool confirmed "Screening completed — reviewed within 7 business days." We are now well past that window with no outcome communicated.
• Opened a Microsoft 365 support case (SR# 2606200050000510) and spoke to support by phone. They confirmed Hardware enrollment sits with a separate team they cannot reach or escalate to, and redirected us to general contact channels that don't route to Hardware.
• Every channel says "not our department," and the team that owns this appears unreachable through standard support — hence more than a month with no progress.

Reproducible steps:

1. Sign in to Partner Center with our enrolled account.
2. Open the Hardware workspace.
3. Result: "your Partner Center account has been deactivated" → restrictedaccess?reason=Deactivated. No path to the driver submission page.

What we need: A Partner Center / Hardware Developer Program team member to check why the workspace is deactivated and what the questionnaire-review outcome was, and to reactivate the Hardware workspace so we can submit our driver. Happy to verify ownership through any private/official channel you prefer.

Thank you — a resolution here would be genuinely appreciated after a month of being routed in circles.
