Hello,
I am having the exact same issue. For me the culprit is a driver called lsi_sas2.sys, but the rest of the screen is identical.
The problem started when I added some drivers to WinPe x86. I have since removed those new drivers by deleting the appropriate folders as per this article ..

but now I am unable to rebuild the WinPe config.
The bootwiz.log file in _:\Program Files\Altiris\Deployment\Logs shows that the driver lsi_sas2.inf was successfully added, yet WinPe4 crashes.
How do I get WinPe back to a working state?
Thanks
