I feel for you. Do you have a personal computer that you can control? I
see that you are working in a Windows environment. Many times I installed
all the packages one machine then just copied the .emacs.d directory
to the other machine, with  most packages working as expected.

If this is an option for you ESS might work out of the box as well. You
might just have to let ESS know where to find R.

Alternatively, for ESS you also have the git repo

You have more information in the manual

As far as I understand ESS is supposed to work even without compiling it
on your machine. Although it won't provide the best experience but is
expected to work.

I also note that you are running R 3.5. From the 4.2,
R uses UTF-8 as the native encoding. This has been a real pain before.
