If you encountered an issue with your testing space photo not meeting the requirements for the AZ-900 exam, it is important to follow up with the appropriate support channels. Since you mentioned that the proctor requested another access code but you have not received it, I recommend reaching out to Microsoft Certification Support for assistance. They can help you resolve issues related to exam access and provide guidance on how to proceed.
You can find the necessary support through the Microsoft Certification Support page or forums, where moderators can respond to your inquiries.
