Started getting "R encountered fatal error. The session was terminated." error when launching R Studio

is never going to work with my installation of the release version. Because

pkgutil --check-signature /Applications/

Package "RStudio":
   Status: package is invalid (checksum did not verify)

leading to

zsh: permission denied: ./

which could in theory be fixed by a deep dive into the directory tree looking for opportunities to chmod +x, but that's not something that anyone should be doing except on a spare box.

Elsepeth+360 is signed, but still not executable from shell, so diagnostics cannot be called with that command.

RStudio 2022.12.1+360 "Elsbeth Geranium" Release (974ce9490cc3e0e75855dbf216047027498ccc56, 2023-01-18) for macOS

Still stuck with this

Created on 2023-01-20 with reprex v2.0.2

The trouble is that I can't tell how RStudio is setting $PATH so I can't tell where to fix it.

See my workaround.
