///Rosetta fix: 

Running softwareupdate --install-rosetta fixes it for me.
(I ran that as part of installing Docker as per https://docs.docker.com/desktop/mac/apple-silicon/; since that appears to be a compatibility layer for older Mac binaries, I wondered if it might also fix this problem, and it seems to!)
