Stan fails to start

Question

I am using R 4.2.0 on Windows 11. When I load the rstan library, the R session is aborted. It says, "R encountered a fatal error. The session was terminated." See the screenshot below.

Answer 1

I reinstalled the most recent version of everything: R (4.2), RStudio (2022.02.2 Build 485) , Rtools (4.2) , rstan (2.26.x) . Then, I changed the R_LIBS_USER library. I can now run rstan in RStudio. I think changing the R_LIBS_USER solved the problem.
