while you have your C++ source file open, could you run the command C/C++: Log Diagnostics from the VS Code command palette and share those logs here

Could you also get logs from the language server (see https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server)?
