And did for me with 12.4 and now 12.5. If the problems were widespread 
we would have heard immediately after release (now a month ago).

Does the previous version work for you?  It was not immediately obvious 
where to get it from the landing page, but from the pattern of URLs, from

https://cran.r-project.org/bin/macosx/big-sur-arm64/base/

Please see this list's archive for earlier this month for a similar 
issue.  The only suggestion there was a customized macOS.  This looks 
specific to a few people and the rest of us can only guess what is 
specific to them.

As the list's archives show, there are requests to test pre-releases, 
and AFAICS nothing like this was reported before release.  Please do 
test pre-releases in future.
