I have had this same problem with a VS2005 project loaded into VS2022. In my case the problem was due to an issue with header names; specifically there was a "Filter.h" hidden several subfolders deep in the project. VS2022 decided to use this instead of the Win32 filter.h that atlheader.h references. Renaming the file "VFilter.h" and changing the appropriate code references in the project fixed the issue and I no longer get CHUNKSTATE-related errors.
