I was able to update the rlang with the following command & it worked.

devtools::install_github("r-lib/rlang", build_vignettes = TRUE)

However when i loading the rlang using the library(rlang) I am getting the error.

library(rlang)
Error in value[3L] :
Package ‘rlang’ version 0.4.5 cannot be unloaded:
Error in unloadNamespace(package) : namespace ‘rlang’ is imported by ‘vctrs’, ‘testthat’, ‘reprex’, ‘lifecycle’, ‘ellipsis’, ‘usethis’, ‘ggplot2’, ‘tibble’, ‘tidyquant’, ‘htmltools’, ‘pillar’, ‘pkgload’ so cannot be unloaded
and the above error with loading the tidyverse continues.

Restart your R session, and try again. If the problem persists, relaunch your project but download a copy of your files first, just in case.
