自上周以来经过多次尝试，我一直无法运行 Jupyter 笔记本或实验室。我曾经从 Windows 11 的 VS Code 运行，并且有许多 .ipynb 文件，如果我不做任何我所知道的非典型操作，我现在无法连接到内核来运行 Jupyter 笔记本的一个单元。不幸的是，我不擅长计算，无法解决问题。内核在超时之前等待很长时间才能连接。经过多次搜索，我尝试了其他帖子中的一些修复，但没有成功。
我重新启动了 VS Code 和我的计算机，但没有成功。我还尝试在 Jupyter Lab (
jupyter labjupyterprint('hello world')按照SO和其他地方的建议，我尝试使用以下命令卸载并重新安装Jupyter：
python -m pip uninstall -y jupyter jupyter_core jupyter-client jupyter-console jupyterlab_pygments notebook qtconsole nbconvert nbformat jupyterlab-widgets nbclientpip install jupyterlab按照另一个建议，我创建了一个虚拟环境，重新安装了jupyter，并尝试启动一个笔记本实例，但仍然遇到同样的问题。
我尝试按照this SO post升级jupyter。
SO 和许多其他解决方案似乎与将其中一个软件包更新到新版本有关。我尝试过其中一些，但没有成功；不幸的是我没有跟踪所有这些。
我遵循了问题 9014 中的指南，但它似乎并不适用，因为我不知道在完成所有故障排除后如何仍然可以打开活动会话。
如果有人可以提供帮助，我将非常感激。我花了几个小时，并且已经开始将我的所有笔记本文件转换为 .py 脚本，因为我担心我无法解决这个问题。
我正在跑步：
此时，我根本无法从 VS 代码或命令行运行 Jupyter，因为它在几乎无限的时间内无法连接。我采取的 6 个故障排除步骤包含在“问题详细信息”部分中。
在Jupyter笔记本中，它卡在：
'内核正在启动，请稍候...”。
在 VS Code 中，卡在：
连接到内核：Python 3.9.1 64位：激活Python环境“Python 3.9.1 64位”
从我上次尝试复制的命令行输出如下：
