Hi @Kieron Neal ,
Thank you for posting in Microsoft Q&A forum.
What version of Windows ADK you are using? If it is ADK for Windows 11, the workaround is to copy amd64 folder (default path is C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Windows Preinstallation Environment) and then change the name to x86.
Similar threads for your reference:

Thanks for your time. Have a nice day!
Best regards,
Simon
