x12 not running

[Keitaro-Ninomiya]

The following error arises when using the x12 function.
It was running fine until the latest update.

Could you please look into this?

dta=data(AirPassengersX12)
xts <- x12(AirPassengers)

The error is unfortunately not very specific. Try changing the working directory to a directory where you are sure you can write.
