Hi, have you install the dplyr packages first
install.packages("dplyr")

C:/Users/xxxxxxx/Documents/R/win-library/3.6/rlang/R/rlang.rdb': No such file or directory

Try reinstalling rlang

install.packages("rlang")

Besides installing dplyr you have to load it before using its functions.

library(dplyr)
tbl_df(mtcars)
