各位好，我碰到了一个挺头疼的问题：我的Ubuntu 22.04 amd64系统里，所有系统托盘的Shell扩展突然就消失了，而且看起来都处于未激活状态。我已经试过网上（包括本站）不少常见的解决办法，但都没起效，感觉我的情况有点特殊。如果我其实漏了什么简单的步骤，先提前说声抱歉！

下面是我的具体情况：

• 我检查了「Extension Manager」，顶部的总开关是打开的，我也反复切换过好几次。同时确认了dconf的相关设置，扩展并没有被全局禁用。
• 当然也试过在「Extension Manager」里手动启用扩展：开关能拨到开启状态，但完全没效果。重启Extension Manager之后，开关又变回关闭状态了。
• 运行gnome-extensions list -d命令，只有4个预装扩展显示为「ENABLED」状态，其他所有扩展都是「INITIALIZED」。其中一个正常工作的是桌面图标扩展ding，它确实能正常显示桌面图标。
• 那些处于「INITIALIZED」状态的扩展，就算我用gnome-extensions enable/disable ...命令去操作，状态也还是保持不变。

我已经尝试过的操作：

• 彻底卸载并重新安装gnome-shell-extensions
• 清空~/.local/share/gnome-shell/目录
• 安装「user themes」扩展

下面是扩展列表的示例，包含正常工作的ding和突然失效的espresso：
