Unable to Register - "Legal Entity Already Exists" Error - Cannot Access Support

Hello,

I'm trying to register for the Microsoft Partner Network to obtain an MPN ID for Azure app publisher verification, but I'm stuck in a catch-22 situation.

The Problem:
When registering through Partner Center, I receive this error:
"A legal entity matching the request payload already exists when creating the legal entity"

The Catch-22:
I cannot create a support ticket because:
- Partner Center help form requires selecting a workspace
- I cannot create/access a workspace without completing registration
- I cannot complete registration due to the duplicate entity error

What I've Tried:
- Searching for existing accounts within my organization - no one knows of any
- Attempting to create a support ticket - blocked by the workspace requirement
- Looking for alternative support channels - all redirect back to Partner Center

What I Need:
Either help locating an existing account for my company, obtaining the existing MPN ID, or resolving the duplicate registration issue.

Has anyone successfully resolved this? Is there a direct contact at Microsoft Partner Support who can help?

Any assistance would be greatly appreciated!

Thank you.
