Enrollment fails with "An unknown error occurred" — Case ID 102950775627

I'm trying to complete Apple Developer Program enrollment and consistently hit the following error page:

developer.apple.com/enroll/error — "We are unable to process your request. An unknown error occurred."

This happens [at what step? — e.g., after submitting payment / after entity verification / immediately on clicking Enroll].

I've already opened a support case (ID: 102950775627) but haven't heard back. Has anyone else run into this, or found a workaround? Any guidance appreciated.
