Description

This is very similar to https://github.com/microsoft/vscode-cpptools/issues/11761 and may have the same root cause, but a redundant IntelliSense update is insufficient to remove the issue. (It appears to require additional updates, possibly only a preparse, to work itself out):

This also repro's in VS.
