Why would script call round_any despite not being explicitly called?

I've been struggling with this script for the past month and I still haven't been able to answer this question. I know round_any is used in the plyr package but I don't even load it. I checked all my other packages using ls("package: ") and they don't have this function. Nothing else I find online has been able to point me in the right direction. In browser () I am able to see my type is double [4] (S3:integer64). Am I better off just changing my class from integer64 or finding out how to remove round_any?

Error in `mutate()`:
! Problem while computing `..2 = across(...)`.
Caused by error in `across()`:
! Problem while computing column `Property Count`.
Caused by error in `UseMethod()`:
! no applicable method for 'round_any' applied to an object of class "integer64"

Edit: This .r file contains all the functions and I have another .r file that calls them.
