Erreur : package or namespace load failed for ‘conflicted’: .onAttach failed in attachNamespace() for 'conflicted', details: call: NULL error: `fn` must be an R function, not a primitive function

Hi all,
I try to install a conflicted package but t i have an issue

Erreur : package or namespace load failed for ‘conflicted’:
 .onAttach failed in attachNamespace() for 'conflicted', details:
  call: NULL
  error: `fn` must be an R function, not a primitive function

In my code i think that this error provide from a merge of data, because in this part of my code i have also issue

Warning: Error in merge: arguments inutilisés (by.x = c("PO.Label", "Drying.Batch.Name"), by.y = c("OP", "Batch"), all.x = TRUE)

Help me please.

What kind of code do you get that error when you run it?

Once you have closed your session, try the following

Please let me know the error in that case.

install.packages("conflicted")
library(conflicted)

conflicted::conflict_prefer()
