Dear R Developers,
I am having an issue with the renv package and R 4.0.1, which I
suspect is related to base R and not the renv package itself, as with

There is an interesting issue related to "reticulate" R package which

quite an exhaustive discussion:

It is important to maintain the independence of R as a programming language
by itselft, even if it could benefit from Microsoft work (C++ Base Code,
