C/C++ IntelliSense Provider not working with C/C++ extension 1.33.8 #578

Description

EIDE's built-in C/C++ IntelliSense Provider no longer appears to work with the latest Microsoft C/C++ extension (ms-vscode.cpptools version 1.33.8).

The same EIDE project works correctly when I downgrade ms-vscode.cpptools to 1.32.2.

Environment
Embedded IDE: 3.27.2
VS Code: 1.133.0
OS: Windows 11
Toolchain: COSMIC STM8

Workaround

For now, downgrading ms-vscode.cpptools from 1.33.8 to 1.32.2 makes IntelliSense work again.
