VS Code Python扩展激活失败求助：更新后无法加载

今早VS Code的Python扩展完成自动更新后，出现无法加载的问题，期间未修改VS Code配置或添加新扩展。

扩展输出日志如下：

解决建议 #

• 重置Python扩展配置：打开命令面板（Ctrl+Shift+P），输入Preferences: Open Settings (JSON)，搜索所有python.前缀的配置项，备份后删除相关内容，重启VS Code
• 彻底重装Python扩展：先卸载扩展，关闭VS Code，手动删除扩展目录c:\Users\tmorg\.vscode\extensions\ms-python.python-2023.2.0，重新打开VS Code后安装最新版扩展
• 清理VS Code缓存：关闭VS Code，删除%APPDATA%\Code\Cache和%APPDATA%\Code\CachedData目录，重启后尝试加载扩展
• 回滚到旧版本扩展：在扩展面板找到Python扩展，点击齿轮图标选择「Install Another Version...」，选择更新前的稳定版本（如2022.20.0）安装
