Never had that problem before.
I always make my ISOs from scratch, after cleaning cache and extracting Windows ISO to a new folder.
My cfg file is the same.
Only changes:
- latest Windows update
- latest NTLite
Edit: redid everything with KB5022906 instead, same issue.
Edit 2: going back to NTLite v2.3.9.9020 has solved the issue. I have literally just replaced NTLite.exe with the older one.
