Problem to install rstan on R version 3.6.3 (no update to later R version possible)

Dear all,
I tried to install rstan on a windows machine. Unfortunately, I am forced to use R version 3.6.3. I already cofigured Rtools35. So, package installations from source are possible (Configuring C Toolchain for Windows · stan-dev/rstan Wiki · GitHub):

rt_path = gsub("\\","/",pkgbuild::rtools_path(),fixed=T)
rt_bin = paste0(substr(rt_path,1,nchar(rt_path)-4),"/mingw_$(WIN)/bin/")
writeLines(paste0('PATH="',rt_path,';${PATH}"'), con = "~/.Renviron")
writeLines(paste0('Sys.setenv(BINPREF = "',rt_bin,'")'), con = "~/.Rprofile")

remove.packages("withr")
remotes::install_version("withr", version="2.2.0")

I also created a Makevars.win file:

dotR <- file.path(Sys.getenv("HOME"), ".R")
if (!file.exists(dotR)) dir.create(dotR)
M <- file.path(dotR, "Makevars.win")
if (!file.exists(M)) file.create(M)
cat("\n CXX14=$(BINPREF)g++",
"CXX14FLAGS += -mtune=native -O3 -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2",
"CXX14FLAGS=-O3",
"CXXFLAGS+=-std=c++1y",
"CXX14FLAGS+=-std=c++1y",
  file = M, sep = "\n", append = FALSE)

According to RStan Getting Started · stan-dev/rstan Wiki · GitHub you should install the package “StanHeaders” and “rstan” from source. If I do so, I get following error message for the “rstan” package.

install.packages("rstan", type = "source")

If I install older versions of “StanHeaders” and “rstan” , the installation worked, but I get the following error message, when triying to run the example stanf code:

Can anybody find I solution for my problem? It would be very appretiated.
Thanks in advance

Can you try the preview version of rstan:

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

Thanks a lot for your answer, andrjohns.

If I install the packages with compilation (it is a pop-up window, in which I can choose yes or no), then I get the following error message:

If I do not use the compilation approach to install the packages, then the installation works. But running the example resulted in following error (very long output. I only show the first and last lines):
