Try removing ‘C:\Users\Intel\Dropbox\PC\Documents\R\win-library\4.1/00LOCK

Error in library(epiR) : there is no package called ‘epiR’

R has problems with cloud-synced folders (Dropbox in your case), I recommend you to set your package library in a non-synced folder.

You can change the default library folder by setting your R_LIBS_SITE environmental variable in a .Reviron or .Rprofile file. For example:

# In a .Renviron file you can set it by adding a line like this one with the desired location 
R_LIBS_SITE="C:\\Program Files\\R\\R-4.1.2\\library"
