What's your call - player entering without being beckoned?

Even if one official blew the play dead erroneously, if the crew recognized the error, shouldn't the officials have forced the substitute to wait for the next dead ball to enter?

that can happen sometimes. score keeper blows the horn after it's already in play and if it kind of disorients the players and some of them stop, you may see them kill the play, take the ball OB again and make that sub wait until the next dead ball to enter
