problem with smooth package

Fortran must die
#1
Code:
library(smooth)
Loading required package: greybox
Error: package or namespace load failed for ‘greybox’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘rlang’
Error: package ‘greybox’ could not be loaded
I have used this many times. I am not sure what is going on. Actually none of my packages work.

Bizarrely the issue seems to have been rlang whatever that is. When I reinstalled it the problems with the other packages went away.
