Multiple Intellisense server crashes `handle_update_intellisense`, `handle_initialize`

Environment

• OS and Version: 22631.3447
• VS Code Version: 1.95.3
• C/C++ Extension Version: 1.23.2

Bug Summary and Steps to Reproduce

Bug Summary:
I am on an environment with configuration provider (homemade). With the latest extension version, The Intellisense server crashes very often, making the extension unusable.
When writing some code, the server crash randomly with the error IntelliSense process crash detected: handle_update_intellisense.
It tries to restart, but crash instantly, with this error IntelliSense process crash detected: handle_initialize.

Restarting VSCode make the Intellisense server work again, but then crash quickly after typing some code.
I don't think it can come from the configuration provider, nothing changed in the last 6 months, and it worked without issues until this version.

I attached to the server to retrieve the first crash. It seems the crash comes from an invalid pointer dereference
Exception thrown at 0x0000000140196619 in cpptools-srv.exe: 0xC0000005: Access violation reading location 0x0000000000000030

The subsequent crashes seem to be instant, and I can't attach to the process in order to check the callstack.
I also created a dump for the crash link

Additional context

Start by analyzing the provided cpptools-srv.exe call stack and crash dump, focusing on the handle_update_intellisense and handle_initialize failures and the reported configuration-provider arguments. Reproduce with the listed VS Code, C/C++ extension, Windows, and MSVC settings; done means IntelliSense no longer crashes while typing or restarting under the reported setup.
