Posting #131900 (comment) from @Fidget-Spinner here for visibility:

I'm busy right now but from the brief look I did, it seems homebrew changed the directory of where clang 19 is installed. I can only fix it tomorrow, but if you want to take a try you can fix the directory in the CI file today #131895 (comment)

I've got time so I can update the CI.
