Tag not monitored by Microsoft.
The error shown in the screenshot corresponds to ERROR_VUE_WIDE_BLOCK, which indicates that the Pearson VUE account has been blocked, typically due to multiple failed payment attempts.
To resolve this and schedule the AZ-104 exam (even when using a corporate voucher), contact Pearson VUE support and ask them to review and remove the block on the account. Use the Pearson VUE support options linked from the Microsoft Certification Support page. After the block is lifted, return to the exam scheduling flow and apply the voucher during checkout.
If additional help is needed with certification- or profile-related issues beyond the Pearson VUE block, open a case with Microsoft Certification Support.
