Unable to complete Partner Center Enrollment

Hello,

I am trying to enroll in the Microsoft AI Cloud Partner Program.  I can get through the process (fill out company information, etc.) but when I go to the final acceptance form and click submit, it constantly throws an error:

I can sign in to the Partner Center but cannot open a support ticket because the "contact support" dialogue has no entry for workspace and will not let me enter anything:

Is there a workaround to submit a ticket on this?
