Restricted from the Hardware Portal

We previously had access to the Hardware Center that allowed us to submit our signed drivers and get them signed by Microsoft. However it appears a change in legal information expectations caused our legal information to become correct, which in turn caused our Hardware Center access to become restricted. I have fixed the legal information and can confirm that it now shows us as "Authorized" with a green check mark, but we are still restricted from the Hardware Portal. The AI Support Bot does not allow us to submit a ticket to resolve this, because we don't have a workspace. We can't create a workspace because we cannot access the hardware portal. Similarly, there is no "?" support option (as the AI support bot suggests there should be) that would allow us to submit a ticket directly.

I have spent the entire day going in circles trying to restore access to the Hardware Center and I cannot submit any support tickets, or get our access restored, despite our legal information being correct and up to date. How do I get our Hardware Center access restored, since I do not have a workspace?
