What does :log-open say?

[erasin]

:lang will show current language of file type.
:lang cpp set language of current buffer.

I have this problem too, only for C++ file.

I had this same issue (on windows). Uninstalling and then reinstalling the latest vc redist worked for me. I also fetched and built grammars.

Maybe i missed something. I rebuilt it and repackaged the runtime together, it now works fine.
