To Reproduce
I have installed R 4.5.0.
I run these commands in RStudio in a fresh session:

install.packages("cmdstanr", repos = c('https://stan-dev.r-universe.dev', getOption("repos")))
library(cmdstanr)
library(posterior)
library(bayesplot)
color_scheme_set("brightblue")

check_cmdstan_toolchain()
The C++ toolchain required for CmdStan is setup properly!

I have installed Rtools45 previously, and saved in C:/

Then run in RStudio this command:

install_cmdstan(cores = 2, overwrite = TRUE)

After all process of installation is done, I get the warning:

"Warning message:
There was a problem during installation. See the error message(s) above."

With a part of the message appearing by the end written above, at the first part of this issue.
