Problems to load packages in memory in RStudio


I´m trying to use the following packages in RStudio: ggplot2, dplyr, tidyverse.

I have no problems wtih the instalation

And I can find the propers folders created in the R directory but when I try to charge in memory the package I get this error:

Error: package or namespace load failed for ‘ggplot2’ in readRDS(nsInfoFilePath):

Any help, please ?
