IntelliSense database gets into bad state after extension update

Bug type: Debugger

Describe the bug

• OS and Version: Ubuntu 20.04
• VS Code Version: 1.60.1 83bd43bc519d15e50c4272c6cf5c1479df196a4d x64
• C/C++ Extension Version: v1.7.0-insiders
• Other extensions you installed (and if the issue persists after disabling them): CMake and CMake Tool and so on.
• A clear and concise description of what the bug is.
  When I use this function [Find All References] to find a method where it is called, the result is none! But it is good at v1.6.0

To Reproduce
Please include a code sample and launch.json configuration.
Steps to reproduce the behavior:

1. Find a any method in a cpp class
2. click right and choose the [Find all References] function
3. It will tell you no results.
4. It is very disappoint!

Additional context
I want to use v1.6.0, but the VSCODE always auto install the v1.7.0-insiders for me. But the v1.7.0-insiders has a bug for [Find all References] when I'm viewing code! I don't how to close the auto install. If you can control it, please give me a switch to close auto install function. Or you can recommend new version for me, I can choose whether to install it, don't auto install it. I feel very uncomfortable!
