Hi, this is the first time I have had this issue when integrating updates into a clean Microsoft ISO, I have tried several times but keep getting the same error. I am trying to integrate KB5068861, the prereq (KB5043080) integrates fine but I get these errors:

If I open the updates cache folder, "windows11.0-kb5068861-x64_acc4fe9c928835c0d44cdc0419d1867dbd2b62b2" is present. Any ideas how to fix? This CU is huge so installing it post-OS install is too time consuming.
Thanks
