Windows10下Jupyter Notebook启动后无法连接内核求助

今日发现Anaconda Navigator意外退出，此前Jupyter Notebook可正常使用，但重新启动时出现错误提示：

无法建立与Notebook服务器的连接。Notebook将继续尝试重新连接。请检查您的网络连接或Notebook服务器配置。

通过命令行启动时的日志如下：

已尝试以下方案，均无效（操作系统为Windows10）：

• 降级tornado版本
• 创建新的conda环境
• 卸载重装Jupyter Notebook
• 重装最新版Anaconda和Python

更新
执行jupyter kernelspec uninstall my_env删除自定义环境后，命令行启动Jupyter Notebook的错误日志如下：
