tidyverse namespace fail

[startz]

Hi folks, I have the dreaded "namespace load failed." Any suggestions? I have removed and then installed tidyverse. I'm running R 4.1.0 on RStudio 1.4.1717 on Windows 10.

> library(tidyverse)
Error: package or namespace load failed for ‘tidyverse’ in namespaceExport(ns, exports):
 undefined exports: R6Class, is.R6, is.R6Class
In addition: Warning messages:
1: package ‘tidyverse’ was built under R version 4.1.1 
2: S3 methods ‘as.list.R6’, ‘format.R6’, ‘format.R6ClassGenerator’, ‘plot.R6’, ‘print.R6’, ‘print.R6ClassGenerator’ were declared in NAMESPACE but not found

Try

install.packages("R6")

Thank you @nirgrahamuk. Turns out that

install.packages("R6")
install.packages("pillar")

did the trick.
