Well, it's actually a rare scenario caused by Win11 not getting new LCU for considerable time, and a limitation in WUI10 (it detect the current LCU KB5005635 as installed in 22000.194 ISO, therefor it skip re-installation)
I'm trying to download it. mistake. Status Legend: (OK)ownload completed. Unable to retrieve data from Windows Update servers. Reason: EMPTY_FILELIST If this problem persists, most likely the set you are attempting to download was removed from Windows Update servers.
They do. Or at least as much as I can see. I already made an LTSC 2021 image with a langpack and it seems to have some tiny glitches here and there, but after you update it(or maybe even offline service it?) they seem to go away.
