I think the problem may come from incompatible package versions. You can try with:

update.packages(ask = FALSE, checkBuilt = TRUE)

If it doesn't work, reinstalling all packages the problem may disappear (code from here):

package_df <- as.data.frame(installed.packages())
package_list <- as.character(package_df$Package)
install.packages(package_list)
