I have seen the message after I terminated R, as one of options proposed while I was constantly getting this message R is taking longer than usual
I am using R x 64 Version 4.1.0
RStudio 1.4.1717, "Juliet Rose" (df86b69e, 2021-05-24) for Windows
Several times, I have attempted to uninstall(and clean AppData)/ reinstall both R and Rstudio, with no improvement.
