Hello,
I hope you are doing well.
1,According to the official article, this is by design. The last supported version of 32-bit WinPE is available in the WinPE add-on for Windows 10, version 2004. The 32-bit versions of Windows PE (WinPE) in the WinPE add-ons for Windows 11 and Windows Server 2022 aren't supported.

2,A similar thread for your reference: Unable to update X86 default boot image after upgrade to ADK 2262 on MEMCM 2203.
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.
3,MDT doesn't officially support Windows 11 and Windows Server 2022 operating systems. It's recommended to use SCCM to deploy Windows 11 to client computers. Refer to:

Hope it helps. Feel free to contact me if you have any concerns/queries.
Best regards,
Simon
