Error Information: code 6, cannot access R

Description of issue - I installed the latest R and RStudio versions today, as I have for many years without problems, but today RStudio crashed when I tried to open it

Attempted steps taken to fix - deleted all R versions and reinstalled latest (R-4.1.2-arm64), which I can access outside of RStudio; deleted .Rprofile file, did Sys.which("R") and got message: no matches found: Sys.which(R)

System Information:

  • RStudio Edition: (Desktop or Server) Desktop
  • RStudio Version: 2021.09.2+382
  • OS Version: Monterey 12.0.1
  • R Version: R-4.1.2-arm64

It looks like RStudio is trying to load R as though it's an Intel version, but you've installed an Apple Silicon version. Do you have Apple Silicon (M1) hardware? Does R work at the command line? You might also try installing the version of R for Intel to see if that addresses the issue.

absolutely correct and works perfectly with the proper version - thanks for pointing it out, much appreciated
