Hi there @LucyH.. Since you didn't mention this, I have to ask -- have you filed a dispute for a charge on your Square debit card recently? If so, that would definitely deactivate your card and you'd have to obtain a new one.
Otherwise, the only other cause of this I can think of is in your debit card settings. Go there on your web dashboard and see if the "lock card" toggle is on for some reason. If it is, you should be able to toggle it off.
If neither of these applies to you, let me know and we'll get the Community moderators involved.
