尝试更改textmeshpro文本时出现Unity错误

Question

我想知道是否有人可以帮助我，我收到此错误：NullReferenceException: Object reference not set to an instance of an object PlayerStone.AdvanceMoveQueue () (at Assets/Scripts/PlayerStone.cs:197) PlayerStone.Update () (at Assets/Scripts/PlayerStone.cs:109) 我不确定为什么在我引用我的对象时会弹出此错误。我想知道是否有人可以帮助我解决这个问题，我尝试了一系列解决方案，您可以使用// //从我的代码中看到这些解决方案，但是尝试更改文本的方法均无效。我将附上我的剧本和一张照片。
