The error ERROR_VUE_WIDE_BLOCK indicates that the Pearson VUE account is blocked, typically due to multiple failed payment attempts.
To resolve this and be able to proceed from Microsoft Learn to the Pearson VUE online exam platform, contact Pearson VUE support and request that the block on the account be lifted. After Pearson VUE removes the block, return to Microsoft Learn and try scheduling the exam again.
