Interesting. I am on 12.0.1 and there is no popup, but there is a
crash report with

Exception Type:        EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid))

Possibly the popup was added in 12.1 beta.

FWIW I did some local builds on a Big Sur machine with Xcode 12.x with
the same settings as the CRAN builds (for readline support primarily),
and those (https://files.r-hub.io/macos/readline/) work fine on
Monterey as well.
