Cannot install any package of R

Question

I was trying to reinstall a package beacause I have the following error:

A version of this package for your version of R might be available 
elsewhere,        
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/Radmin.html#Installing-packages

Here's the code:

install.packages("tidyverse")
install.packages("sf")

I tried to install different versions of R but I'm still having the same issue. And now I cannot install any package at all, because of the same reason

Anyone has experienced any related issue?
