Dear Jeff and R friends, I fixed the issue. The problem was due to the fact that I had R version 4.1.2 and installed the newer version R 4.2. Since RStudio automatically points to the latest R version installed, there were a lot of packages that were not installed.
I just made RStudio point to an older R version and the issue was solved.
