Hardware Developer Program shows "Active In" but the Hardware workspace does not appear — cannot open a support ticket (Workspace dropdown empty)

I'm the Global Admin for our company's Partner Center account and I'm stuck in a catch-22 that I can't resolve from the portal.

Current state (all complete on my side):

• Account verification: Authorized (Legal info).
• Hardware Developer Program: shows as "Active In" under Account settings > Programs.
• EV code signing certificate: Active (Manage certificates).

Problem:

• The Hardware workspace does NOT appear on my dashboard, so I can't access Hardware > Drivers > Submit new hardware.
• I can't open a support ticket either: Partner Center's Help + Support form requires selecting a Workspace, but my Workspace dropdown is empty ("No results found").
• The Windows Developer Support Copilot only loops through section menus (Azure / M365 / CSP / Apps and Games / None of These) and never creates a case.

Already verified on my side:

• Signed in with the global administrator account used for registration; roles confirmed under My Access.
• Checked the global admin mailbox (including junk) and My Preferences preferred email.

Could a Microsoft engineer/moderator please reach out so I can privately share my account identifiers, and investigate the backend registration/provisioning status — and resend the business questionnaire if it was never delivered — so the Hardware workspace can be provisioned? I can provide Seller ID, tenant, and HAR/PSR logs privately on request.

Thank you.
