Hi there,
tidyverse is a package bundle. One of the packages that are loaded with library(tidyverse) appears to in turn rely on another package fs. It seems, this was not installed. Open a new session of R (Ctrl + Shift + F10) and install the respective package:
install.packages(`fs`)
restart again and try to load tidyverse. If it still fails look closely at the error message and install further missing packages.
Hope this helps!
