Thanks for the report! I believe this is an issue with the homebrew distribution. We have no control over that, so it would probably be best to report it on their issue tracker (https://github.com/Homebrew/homebrew-core/issues I think?).

A user at rust-lang/cargo#13795 indicated that reinstalling llvm@17 helped them.

Thanks
brew install llvm@17 resolved the issue

Also do brew reinstall rustc , after above to fully resolve this issue
