R `object not found` error dplyr select when variable is present

Question

getting this error for all dataframes / tibbles and can't figure out why.

R Version: 3.6.0 - I'm working out of a googledrive folder, but have been for months without issue. - it is a git-connected folder aswell - I have some functions that use {{}} tidyeval, but I get the error with or without the functions

mtcars %>% rename(mpg2 = mpg)

Error: object 'vctrs_new_data_frame' not found

error shows:

<error/rlang_error>
object 'vctrs_new_data_frame' not found
Backtrace:
  9. dplyr::rename(., mpg2 = mpg)
 11. tidyselect::vars_rename(names(.data), !!!enquos(...))
 12. tidyselect:::rename_impl(NULL, .vars, quo(c(...)), strict = .strict)
 13. tidyselect:::eval_select_impl(...)
 14. tidyselect:::with_subscript_errors(...)

backtrace shows:

Any ideas? My code was working fine last week!!

Can you try mtcars %>% dplyr::rename(mpg2 = mpg)%>% names# [1] "mpg2" "cyl" "disp" "hp" "drat" "wt" "qsec" "vs" "am" "gear" "carb" as this is working for me — akrun
Looks like some env issues. Do you always save env while exiting — akrun

Got an answer from the helpful tidyverse dev team which worked:

remotes::install_github("r-lib/vctrs")

Had to remove the LOCK file associated to vctrs, then it worked. Thanks all for your comments.
