Hi Daniel,
That’s an easy fix, you’ve just missed a step in the Getting Started instructions.
There’s a bug with the withr package versions > 2.2.0 on Windows with RStan, this causes that error when you have anything in your Makevars.win file. To fix, you just need to manually install version 2.2.0 and then not update:
devtools::install_version("withr", version="2.2.0")
Yes, yes, I downgraded withr, but I always forget to uncheck this package when updating all packages ;-) That’s why I now tried the alternativ solution that works with withr 2.3
Are there any negative sideeffects when not having the above mentioned configuration in makevars.win?

Yes, your models will run a little slower. The compiler flags:
-mtune=native -O3 -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2
instruct the compiler to aggressively optimise (-O3) the compiled code, and take advantage of any available SIMD instruction sets (-m*) for the given CPU
