Are there any entries in Console.app that might help triage?

Have you tried creating a new user on your Mac and seeing if that account has 
issues performing the same tasks your user account is having?

Having said that, I just grabbed "Mac OS X GUI rev. 7843 for R 4.0.x" from 
mac.r-project.org (I never use R.app nor do I keep it installed unless testing something) 
and am running R 4.0.1 on latest Catalina beta — 10.15.6 Beta (19G36e) — and it crashes 
every time I try to open a .R file (crashlog

Hi,
2 weeks ago I installed R 4.0 on my new Catalina machine. Things seemed to be 
working fine.
Today I installed R 4.01, and now I can't open any FILE.r - no matter what way 
I try, i.e. double-click the file, drag/drop, or open from the R GUI menu,  R 
hangs with the beachball.
I tried giving R full disk access and other privileges via Security settings; 
no help.

So I deleted R 4.01 and reinstalled R 4.0, and dang if I no longer can open 
files any more!  I've tried all the suggestions in the previous thread in this 
mailing group; no help.

What else can I do, or delete, or uninstall, to at least get back to where I 
was? Right now I'm basically DIW.
