Hello there,
Check if you have the latest playlist downloaded.
The Windows Hardware Compatibility Program uses an official playlist to determine which tests must be successfully completed for devices and systems to be compatible with Windows 10 and Windows Server 2016. The latest playlist can be downloaded at https:// sysdev.microsoft.com/en-US/Hardware/compatibilityplaylists .
This playlist is optional for the next 90 days, after which it will be required by the Hardware Developer Portal, and previous playlists will no longer be accepted. Published playlists can be used for submissions for 90 days after the next playlist update.
The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue. https://social.msdn.microsoft.com/Forums/office/en-US/e36d6166-fa65-4eed-8065-8662cc966f7b/hardware-certification-playlist-validation-failed?forum=whck
