After UNSUCCESSFULLY trying windowsinstallationassistant for every solution found on the net because I wanted to avoid a clean installation from ISO USB, Idecided to proceed to a clean installation. I was surprised by several facts that:
1) 22H2 version didn't recognize my 2TB. I used a IRST v.18 which perfectly worked with windows 11 version 21H2. I downloaded the newest version (v.19) from intel web site and 22H2 installation assistant successfully recognized my samsung pcl gen 4 2TB size.
2. During the installation, I was very surprized to see that all zenbook duo 14 pro drivers were totally not recognized, wifi included. So I had to continue with the limited option installation.
I redownloaded wifi driver to my samsung fold 3 and fortunately windows 11 22H2 opened my fold 3 drive and installed asus wifi driver.
So, I found now the reason why windowsinstallation stucked at 100%. The issue comes from the intel IRST.
Unfortunately, I didn't use the option: install the IRST new exe version before retrying the upgrade to 22h2 by windowsinstallationassistant.
So, if you are facing the problem, please install the IRST exe (v.19) and retry the windowsinstallationassistant to see if the problem persists...
OUF!!! From now, I have to spend hours and hours to reinstall my licensef softwares...
