RStudio is not picking my latest R version

[JohnHCarsonJr]

Description of issue -

I have R-4.3.1 and R-4.3.2 installed from source in ~/R with libraries in R/x86_64-pc-linux-gnu-library/4.3. My OS is POP!_OS 22.04 (a variant of Ubuntu 22.04).

I have the R shell wrapper script at
~$ which R
/usr/local/bin/R

I get no error messages, but R started from the shell runs R-4.3.2 , while RStudio runs R-4.3.1.

Furthermore, if I go to the terminal in RStudi and try to start an R session, it failes with these errors
$ R
WARNING: ignoring environment value of R_HOME
/usr/bin/R: line 249: /home/jcarson/R/etc/ldpaths: No such file or directory

Hi, have you tried this set up in your ~/.profile?

export RSTUDIO_WHICH_R=/usr/local/bin/R

Definitely! Sadly, it did not help.

.profile

cat .profile
