Partner Center enrollment broken for tenant - 410 on legacympnprofile/search and 500 on partnerprograms/enrollments - cannot open ticket (no workspace)

Enrollment cannot be completed for my tenant, on both enrollment paths. Because no enrollment succeeds, no workspace exists, so I cannot open a support request from Partner Center (the Workspace field is mandatory and the list is empty).

Tenant: prea.ro (25780a6c-1973-42fc-acee-7e44d4c91fc2)

User: ******@prea.ro - Global Administrator

Entity: sole proprietorship (PFA), Romania, D-U-N-S 505985244 (validated by the dunssearch step)

Path 1 - Commercial Marketplace (/v3/enrollment/companyprofile/azureisv):

After "Accept and continue", POST /dashboard/account/v3/api/legacympnprofile/search returns HTTP 410 "Endpoint is disabled". Reproduced 2026-10-26 and 2026-10-27.

Path 2 - Microsoft AI Cloud Partner Program (/account/exp/enrollment/programselector/basicpartnernetwork):

GET /dashboard/account/exp/api/partnerprograms/enrollments returns HTTP 500 InternalServerError.

Correlation IDs: 5e8e5d98-8876-4594-95c7-214f4dd4a122, 6173754a-bfde-41a2-9cea-8c9bb805e409 (2026-10-27 ~21:10 UTC).

Service health shows all green. The tenant may be holding a partial enrollment record from the failed attempts.

Please route this to the Partner Center enrollment team, or create a support case on my behalf.
