When I open Rstudio, the usual startup message ("R version 4.0.2 (2020-06-22) -- "Taking Off Again" ... Type 'q()' to quit R.") does not appear.
It seems to only appear if I right-click and 'reload'.
I have re-installed Rstudio, and nothing changes. The startup message appears every time I open R, so this makes me think it is an Rstudio-related thing.
