RStudio no longer starts after having switched to 32-bit R

[strobrid]

Error Information:

Description of issue - R studio won't start after having switched from 64-bit R to 32-bit in global options. I don't actually need to use 32-bit R, I was simply investigating why the RODBC package is no longer connecting to a database to which it was connecting just fine until today. Unfortunately, I now cannot launch Rstudio to be able to switch back to 64-bit R.

Attempted steps taken to fix - Uninstalled and reinstalled Rstudio. Renamed Rprofile file in the R home directory and renamed recently saved .Rdata files in case one of these was causing the issue.

System Information:

• RStudio Edition: Desktop
• RStudio Version: 2022.07.1+554
• OS Version: Windows NT 10.0; Win64; x64
• R Version: 4.0.5

You can change it by holding the Ctrl key while opening RStudio, then you should see this menu.

thanks. i just did this and, unfortunately, got the same thing. i also tried the "specific version" option with no luck. R itself works. i guess i should upgrade to latest version of R? i'm not sure why this is just happening now because i've been using this combination of R and Rstudio for several months now.

sorry, it does work now. I had renamed the Rcmd_environ and Rconsole and Rprofile.site files in process of trying to figure out why Rstudio wouldn't load, but i guess these also caused R not run. i removed my renaming prefix from them and now regular R console runs and Rstudio also runs now that your ctrl suggestion got me back into 64-bit mode. thanks for that! i never would have figured that out on my own.
