When I try to log in to my account it says, error code crossbow ". I've already tried to restart the switch, restart minecraft, archive minecraft and log out of my account and log in again
What exactly do you want to know now? Why does it say "Error Code: Crossbow" or how you can log in again?
Actually both
Error seems to be already known / reported.
