Yes, there were some reports of this with Server 2022.
I can't reproduce it and checking if a file exist, is the most basic feature.
I could only assume something like an antivirus or filter driver that does interfere,
but it does not happen if I install Server 2022 with WinNTSetup. The new system does not show any problem.
The version display of wimlib and wimgapi will be removed, it just leads to wrong assumption and
some people start updating them manually, what only causes problems.
