Sorry for the minimal & probably uninformed report, I'm hitting this with the latest brew build on macOS.

$ /opt/homebrew/opt/llvm/bin/clang-tidy --version                                                                                                                                                                                                                                                            

Homebrew LLVM version 21.1.0
  Optimized build.
