大佬们，这个是错你们有吗？（不是必现，但是出现的概率挺高的）

同求原因,貌似和删除节点与在update中排序节点有关,但是做了判空了,浏览器没事
遇到同样问题

我也遇到了，什么情况
解决了吗，我也遇到了
在load预制体或实例化期间物体或UI，过程中暂停了，就会出现，确保实例化完成后在暂停。
请问暂停指的是什么意思？
同问，编辑器上必现，导致每次都要重新运行一次才正常
能提供个复现的demo么，我们也在努力排查这个问题，如果有复现的demo有助于我们解决问题
我们项目昨天有个地方大约90%的概率会出现这个报错，今天没试出来。
在cocos Editor内运行会出现，浏览器运行没出现。
我昨天根据提示的行号，定位到是node类的代码，这里的_children的值是null，加了两个warn输出this.name和this.parent都是空的
调用暂停方法暂停游戏->创建物体->取消暂停->销毁物体，就会出这个错误
3.8.3试了下，并没有出现这个问题
3.8.3在insertChild之后立马destroy就会报这个错
3.8.4还是有同样的问题
3.8.5试看看
是否可以提供个demo，这样有助于我们排查问题，因为我不好复现这个问题，感谢
