Hi,
I am also having the same issue. I have R version 4.1.2 for aarch64-apple-darwin20 and have tried the latest stable RStudio Build (2021.09.1+372) as well as a daily build from today (11/20/2021), and for both have received the same error messages when opening RStudio. I tried the preview release too and that didn't work.
I am able to run R from my terminal and from within Rapp. I am on macOS Monterery Version 12.0.1 with a Macbook Air M1 2020 (16 GB, 1TB). To date, I have had no issues running the arm64 builds of R through the Intel-based RStudio build until I restarted my computer after various software updates. I've tried uninstalling and reinstalling both R and Rstudio, and have not found a proper solution.
Hoping someone out there knows what's going on. I have several projects I'm working on in RStudio that I only have time for on the weekends.
Maybe we need to try and install older versions of both until this gets sorted out?
The process output: " The R session process exited with code 6 ."
