Que estranho, quando crasha mostra alguma mensagem ?

Sim. ele está dando erro na linha "local super=Classe("Grade",LuaObject,function() ".
Mensagem de quando crasha: https://prntscr.com/pubyu4

DNL291 · November 8, 2019

Tem certeza que o crash tem relação direta com esse código?

A classe não está completa, provavelmente tem outro arquivo separado fora esse código postado.

Se tiver algum problema com esse script, é mais provável que seja por mal uso.
