I tried removing those Pref and Cache items. No help
It doesn't matter how I try to open a file: double-click the file, drag&drop, from the Rgui File menu or the icon in the header of the console window. They all hang the same way. I tried turning off DefaultFolder and QuickSilver; no help. I'm happy to try other experiments -- about the only other "unusual" thing in my setup is USBOverdrive.

Just in case: 10.15.5, 3.6 GHz quadcore i3, 16GB Apple-installed RAM , APFS, SATA hard drive (not SSD)

Thanks for the reports. Unfortunately, I still cannot reproduce it on Catalina 
- neither with 4.0.1 nor 4.0.0.
Can someone post exactly how to replicate? (How do exactly you open the file? - 
the Open dialog works fine for me...)

Note that the GUI is independent of R and compatible up to the patch version, 
i.e. the 4.0.0 GUI works with R 4.0.1 and vice-versa. You can also just 
download the GUI from
https://mac.R-project.org
and run it from the image, you don’t even have to install it.

The only changes in the GUI for 4.0.1 were in the colours for dark mode, so 
file handling behaviour didn’t really change.

Some places to remove to try if it has any effect:

rm -rf ~/Library/Caches/org.R-project.R
rm ~/Library/Preferences/org.R-project.R.plist

Thanks,
Simon

This sounds exactly like the issue I am still having when I run to open
more than one R script file in R-GUI’s editor. Perhaps it has got worse
with the newer builds?

I'm not sure what to look for in the Reports sections of Console.app,
but I did find this report of R exceeding a diagnostic limit of CPU
usage, which most likely is related to one of the hangs - R.app always
goes full throttle on one CPU core.

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.
