tidyr::spread() gives an Error

Question

SOLVED

Please, help to figure out what might be wrong with the following example.

library(tidyverse)

(freq <- structure(list(Year_of_diagnosis = c(2004L, 2004L, 2005L, 2005L, 
                                             2006L, 2006L, 2007L, 2007L, 2008L, 2008L, 2009L, 2009L, 2010L, 
                                             2010L, 2011L, 2011L, 2012L, 2012L, 2013L, 2013L, 2014L, 2014L), 
                       Sex = structure(c(1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 
                                         2L, 1L, 2L, 1L, 2L, 1L, 2L), .Label = c("Female", "Male"), class = "factor"), 
                       n = c(70L, 180L, 70L, 170L, 70L, 180L, 60L, 220L, 80L, 190L, 80L, 230L, 60L, 210L, 70L, 230L,
                             70L, 220L, 70L, 220L, 80L, 230L)), 
                  class = c("tbl_df", "tbl", "data.frame"), .Names = c("Year", "Sex", "n"), row.names = c(NA, -22L)))

an issue is here:

tidyr::spread(freq, key = Sex, value = n)

it gives the following error:

Error in matrixToDataFrame(x) : object '_tibble_matrixToDataFrame' not found

Update: [credit to @aosmith] reinstalling tidyverse in a fresh session helped.
