Can't get "Code Analysis Mode" to work with ESP-IDF

[Tomblarom]

Environment

OS: Windows 10 22H2 VS code: 1.86.2 C/C++ extension: 1.19.2 ESP-IDF: 5.2 ESP-IDF extension: 1.7.0 Python: 3.11.4

Disclaimer

Actually, I'm not sure if this is a bug or just a dumb newbie issue, but trying to troubleshoot took already way too long. I need proper support. And I contacted ESP-IDF devs first: https://github.com/espressif/vscode-esp-idf-extension/issues/1140

Description

I'm struggeling to get the automatic "Code Analysis Mode" of C/C++ extension to work. I downloaded and installed the latest ESP-IDF v5.2 through the VS Code IDF extension and additionally did it a second time through the online-installer 2.24. With this I'm able to successfully compile. However my environment lacks live/automatic Code Analysis Mode (when I write false C/C++ code it's not beeing detected). By default its on Manual and I tried to enable "C_Cpp.codeAnalysis.clangTidy.enabled": true, but this results in random expections like this:

I found a few issues that are related to my issue, but I can't get figure how to make their solutions work in my environment..

I tried to install the IDF Tool "Clang-Tidy" or esp-tidy, was not able to properly attach it to the C/C++ extension. I tried to change the compilerPath in c_cpp_properties.json to ${config:idf.toolsPathWin}\\tools\\esp-clang\\16.0.1-fe4f10a809\\esp-clang\\bin\\clang.exe (or clang++.exe or clang-tidy.exe), which lead to these exceptions:

Include file not found in browse.path.C/C++
'stdio.h' file not found C/C++(clang-diagnostic-error)

Steps to Reproduce

1. Create the sample "hello_world" project and open it
2. Install C/C++ extension (if not done already)
3. Fix IntelliSenseEngine according to this guide
4. Add the following to settings.json:

"C_Cpp.codeAnalysis.runAutomatically": true,
"C_Cpp.codeAnalysis.clangTidy.enabled": true,

5. Now go to main.c and encounter the previously described error messages
