YCM Fails to Find Project Headers #4291
Description
I recently upgraded my corporate laptop to macOS Sequoia 15.3.1 (24D70). I deleted my previous version of YCM, re-cloned recursively and then built YCM with:
python3 install.py --clangd-completer
My vim version is:
VIM - Vi IMproved 9.1 (2024 Jan 02, compiled Sep 18 2024 15:59:03)

I have checked each path in the Settings and they all exist. The code builds fine using the system clang. I have also tried to use other brew versions of clang/llvm and see the same results.

I am working on trying to run the clangd command to see why it is failing to generate the index.
An example of what I am seeing in vim is:
