Seems like it might be related to a new version of libomp which requires python@3.12 which was not previously required. Maybe there's already a version of python on this machine, so the explicit linking of that version is what's messing things up? No clue just trying to deduce the cause based on error & what changed. @michaelgsharp have you seen this before?
