Intellisense always updating

Environment

• OS and version: W11 Pro (10.0, compilation 22000)
• VS Code: 1.78 (The version doesn't matter. It happens with everyone)
• C/C++ extension: C/C++ Extension Pack v1.3.0 Microsoft
• GDB / LLDB version:

Bug Summary and Steps to Reproduce

Bug Summary:
Every time I save, the intellisense is activated again, indexing the entire project, making it impossible to perform its function, which is to display the methods, properties... as well as the information.

[ - Steps to reproduce the problem - ]

1 - I write the code

2 - When I save anything (right here the intellisense re-indexes the whole project)

Every time I save we get:
1 - Indexing of the entire project.

What it does is:
1 - When I save it sends a notify
2 - That notify indicates that it was saved or there was a change
3 - Index the entire project again.

Additional Information

[Settings -> Intellisense]

C_Cpp: intelli Sense engine
Controls the Intellisense provider in

• "Tag Parser" (No) does not update compile-time errors
• Default (Yes) analyzes errors at compile time.

I can't put it in "Tag parser" otherwise it's like the errors don't work.

Reproduce on Windows with the C/C++ extension, CMake Tools, and the Unreal Engine project described in the issue; save a file while observing IntelliSense indexing. Start with the IntelliSense settings and save/notify behavior, then compare the full-project indexing activity before and after a save. Done means normal saves no longer trigger unnecessary full-project reindexing while compile-time errors remain available.
