That is not a segfault, although they have been seen to cause this 
behaviour.  It more often indicates a security issue: arm64 macOS is 
prone to doing so with incremental rebuilds of R that it thinks have 
been tampered with.

Try installing the .pkg.  (Downloading from mac.r-project.org is far too 
slow at the moment for me to do so, but I recall past troubles with the 
tarballs not seen with Installer packages.)
