I don't have any access to Windows but note that CRAN of course tests Rcpp
and its 2600+ reverse depends on Windows.
On the OS I use all is well with this (and of course in general)

So I suspect something is not tied down correctly at your end; maybe new R

One gets 15 h / months free at posit.cloud (formerly rstudio.cloud), that is
good to just run a quick sanity check like this.
