[R] tidyverse repeating error: "object 'rlang_mut_env_parent' not found"

[Szumiloski, John]

UseRs,

When doing some data manipulations using the tidyverse, I am repeatedly getting the same error message in now three separate situations.  I can write up a reproducible example, but want to lay out the high-level issues in case someone recognizes exactly what is happening here.

The error is:

Error in mut_env_parent(overscope$.top_env, lexical_env) :
  object 'rlang_mut_env_parent' not found

and it occurs in three situations:


1)      Using tidyr::nest() on an output from dplyr::group_by()

2)      Using tibble::tibble() with <name> = <value> arguments

3)      Using dplyr::select() on a tibble to select two columns

Any obvious clues as to what's happening here? The only non-base packages loaded are current tidyverse, forcats, magrittr, readxl and stringr.

Thanks,
John
