Persistent AU10TIX identity verification error and inability to open support ticket

Hello everyone. I am facing a recurring block during the identity verification process in the Microsoft Partner Center using AU10TIX.

I have already performed all necessary checks. The registration data is strictly identical to the presented documents, the RG photo is submitted with excellent lighting, and the selfie is captured without accessories, using the native camera and without using a VPN or restrictive networks.

Despite all criteria being met, the system immediately returns the error message Sorry, we were unable to complete your verification and the profile remains locked.

Additionally, it is not possible to open a support ticket through the partner portal because the system requires the workspace field as mandatory, which we do not have yet due to the current status of the account, completely preventing the submission of support requests through traditional channels.

How can I proceed to solve this problem?

Thank you for your help.
