Unable to purchase a Partner Benefits Package

I'm the Global Admin for our organization (entrusted GmbH) registered in the Microsoft AI Cloud Partner Program, but I'm unable to purchase a Partner Benefits Package — the role required per documentation, "Microsoft AI Cloud Partner Program Partner Admin," cannot be assigned in User Management (no such option/checkbox is visible; only the existing Global Admin role shows).

Additionally, when trying to open the Membership/Offers page, I repeatedly get errors:

• Error ID 2100001, CorrelationId f6d255f8-842c-43e5-a044-9a2f97edd3ef, 29 Sep 2026 06:11:05 GMT
• Second error, CorrelationId 27805d5f-546c-44c8-9929-5ec4e873a6f, 29 Sep 2026 06:14:35 GMT

Goal: Purchase a Partner Success Core Benefits Package. Please advise, either by assigning the missing role or by resolving the access error.

Additionally, the support ticket form itself is broken — the required 'Workspace' dropdown shows 'No results found' and cannot be typed into, so I cannot submit a ticket through the standard flow either.
