I get these error lines as soon as I open the R studion
Error in yaml.load(readLines(con), error.label = error.label, ...) :
object 'C_unserialize_from_yaml' not found
Error in yaml.load(readLines(con), error.label = error.label, ...) :
object 'C_unserialize_from_yaml' not found
Error in yaml.load(readLines(con), error.label = error.label, ...) :
object 'C_unserialize_from_yaml' not found
Then I removed lubridate package & tried installing Rcpp. But it throws up the below
install.packages('Rcpp',dependencies = TRUE)

Warning message:
package ‘Rcpp’ was built under R version 3.5.3
As mentioned, version installed on my machine is R 3.5.2 & this problem has surfaced after recent upgrade to Win 10.
Another pointer is that I used to Admin rights on my machine earlier (prior to Win 10), but don't have any more i.e. I don't have much of rights on the C drive.
