CocosCreator疯狂报错 节点无法删除 UI全部消失看不到

Creator 2.x
#1

Creator 版本：1.90

详细报错信息，包含调用堆栈：TypeError: Cannot read property ‘gizmo’ of null

之前哪个版本是正常的 ：刚学.

编辑器操作系统 ：win

发生过程:
我点击编辑器里隐藏了某个节点(active),然后发现这个节点的sprite无法显示了,我以为是编辑器出错,所以保存了场景然后重启编辑器.之后就开始疯狂报错TypeError: Cannot read property ‘gizmo’ of null,而且所有节点都无法显示了.那个出问题的节点也删不掉.
怎么恢复啊?
