。添加返回主页功能后，控制台出现 [PreviewInEditor]
Cannot read

Failed to

property setter is not supported.的错误，同时编辑器预览可以正常运行，返回主页后再正常进入游戏没问题（虽然控制台还是出现上面的两个错误提示），但是当用游览器预览和扫一扫二维码预览时，每单点击这个返回主页按钮就会出现错误了，出现这 [Browser Preview]
Cannot read properties

TypeError: Cannot read properties
of null (reading '

Cannot read

在使用CocosCreator编程时遇到TypeError，因尝试对null对象设置string属性。开发者在更新函数中试图将计数器每600秒加到stepsLabel上，但可能漏掉了挂载步骤导致的错误。
