Visual Studio 2022启动失败（LoadPackageWithContext未授权异常）求助

• 启动Visual Studio 2022时，短暂显示欢迎窗口（可选择固定或最近解决方案）后陷入白屏冻结，随即闪退。
• 已尝试将版本从17.3.5更新至最新17.5.4、重启电脑，均无效。

安全模式启动VS排查 #

执行以下命令：

cd "C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\"
devenv /SafeMode /Log "%USERPROFILE%\VSSafeModeLog.xml"

弹出错误提示：

An exception was encountered while constructing the content of this frame.
This information is also logged in "C:\Users\MyUserName\VSSafeModeLog.xml".

• 使用Microsoft 365在线授权的Visual Studio 2022 Professional，同事同款授权可正常运行。
• 其他Microsoft 365服务（如OneDrive）登录及使用无异常。

• 更新Visual Studio至最新版本
• 重启电脑
• 执行sfc /scannow命令
• 搜索相关许可证/堆栈跟踪帖子，未找到有效解决方法

在重置整个VS环境前，还有其他解决方法吗？
