AFAIR, you still didn't respond to my questions about the version of
the C++ grammar library you are using, nor tried to upgrade to the
latest version of that grammar library.

FTR, I'm using tree-sitter version 0.20.8 and grammar library from
their Git repository as of June 17 (this is version 0.22.2 of the
grammar library with a couple of changes after that version).  I have
no problems with displaying C++ files whatsoever, and *Messages* is
clean.  I also tried the latest version of the grammar library
(0.22.3), and didn't see any problems there, either.
