Unable to create Partner Center account

Let me start by saying that there are multiple threads on this issue, but the responses I've seen have not helped me to resolve this issue. I've exhausted all of my options at this point.

I am attempting to create a partner center account. I'm based in the United States, and after submitting a valid D-U-N-S and EIN and the required information, I receive this error:

Microsoft runs on trust. We engage in a rigorous set of evaluation and certification processes; as a result your request was blocked. If you require further information please reach out to Microsoft support with reference number: {Reference Number} and transaction ID: {Transaction ID}.

It is not possible to contact Partner Center support or create a support ticket in the partner center as is recommended on other threads and on the Microsoft documentation. When you attempt to create a support ticket, the "Workspace" is a required field, but no options are available because the original error takes place prior to being able to create a workspace.

I want to reiterate - it is not possible to contact Partner Center support or create a support ticket to resolve this issue.
