OpenSlide Python found your Homebrew copy of OpenSlide in /usr/local,
but couldn't load it because it's an x86_64 binary instead of an arm64
binary.  On ARM, Homebrew installs into /opt/homebrew instead.  Is it
possible that your Homebrew installation was migrated from a previous
x86_64 machine?  You might consider removing and reinstalling Homebrew
so you have native ARM binaries.  That should also fix the error
you're seeing.
