Hi,

I don't use RStudio, which is a GUI/IDE on top of R, it is not R.

That being said, a quick Google search supports my intuition, which is that RStudio appears to be able to support multiple R version installations:

RStudio also has their own support venue:

If I read correctly, it looks like you actually installed a "Release Candidate" (RC) version of 3.6.0 for Windows. So you probably want to visit a CRAN mirror and download the release version of 3.6.0:

R version 3.6.0 (2019-04-26) -- "Planting of a Tree"

If you do not want to have multiple R versions on your computer, you can use the normal Windows application uninstall process to remove the older version(s).
