This is actually the result of a change in the dplyr package. You're using fairly old versions of R and Bioconductor, and so the copies of the packages that you have installed are not compatible with this new dplyr. There's quite a few posts on here about the issue e.g. Answer: BiomaRt::getBM Error in UseMethod(filter_)

Two possible solutions are to either upgrade R and Bioconductor to the latest release versions, or downgrade dplyr (and make sure R doesn't automatically update it every time you install something else).
