Just providing a more complete answer for people to follow.

Remove packages with

remove.packages("rlang")

That may not work as you may need to delete the package from your R library. To find where you R library is run

.libPaths()

Once you've deleted the rlang folder from there you can restart R and run

install.packages("https://cran.r-project.org/src/contrib/Archive/rlang/rlang_0.4.9.tar.gz", repo=NULL, type="source") # for specific rlang version, in this case 0.4.9. For latest version can run install.packages("rlang")
packageVersion("rlang") #to check you now have rlang version you want
