Can't install package Psych

It looks like you need to install {mnormt} before {psych}. It should ha ppen automatically but sometimes the installer mucks up.



You have a corrupt package library. Seems like you somehow installed x86_64 packages into your arm64 library. You'll need to reinstall all of these packages.

Since this is the system library, the simplest might be to delete the whole R installation, together with the library, and install R from scratch.
