Legal Name Change Request Redirects to Broken Engage Center No Access Error

Hello Microsoft Support,

I need to change my legal name on my Microsoft Learn / Certification profile so it matches my government-issued ID before my exam.

However, I am completely blocked by a system error loop. Every time I try to submit a support request or edit my profile, the system forces me onto the Engage Center (ecenter.microsoft.com) which displays a "No Access" screen or a completely blank white page because I am signing in with my personal Gmail account (******@gmail.com).

Since the online ticket form is completely broken for personal accounts, please open a secure Private Message thread with me here so I can safely provide my legal name details and upload my verification documents to a human agent.

Thank you.
