各位好，我最近碰到一个特别棘手的问题：在通过远程SSH连接的VSCode里，不管是运行Jupyter笔记本还是Python交互式脚本，每次都会弹出「Failed to start the Kernel. The kernel died.」的错误，折腾了好几天都没解决，想请大家帮忙分析下原因。

我的环境信息 #

• VSCode版本：1.101.2（远程SSH连接，桌面端）
• Jupyter扩展版本：2025.6.0
• Python扩展版本：2025.8.1
• Python Environment扩展未安装
• Pylance扩展版本：2025.6.2
• 操作系统：Linux x64
• 目标Python环境：Conda虚拟环境lico_beorn2（Python 3.13.5），路径~/.conda/envs/lico_beorn2/bin/python

从日志里我揪出几个可疑的点：比如有个旧虚拟环境的解释器被标记为无效，还有内核关闭时出现了URL解析错误。但我拿不准这些是不是导致内核启动失败的根本原因，也完全不知道该从哪入手排查。有没有朋友遇到过类似的情况，或者能帮我解读下日志里的关键信息？
