Incompatibility of the latest versions of R and stan.
There is an incompatibility between the latest versions of R and stan. If you have version 4.2 of R and Rtools then you have this issue. The only fix we are aware of is to install a beta version of stan. There are instructions below on how to do this.

Run these two commands:

remove.packages(c("StanHeaders", "rstan"))

install.packages("rstan", repos = c(https://mc-stan.org/r-packages/, getOption("repos")))
