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

of null和 [Scene] 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
of null (reading '

Cannot read properties
of null (reading '
