Thunderbird 出现了一些奇怪的问题，我真的不知道从哪里开始寻找答案。我无法从 Dock 中打开 Thunderbird。打开时，它在 Dock 中显示为好像打开了多个窗口（多个橙色圆点），即使事实并非如此。我无法单击 Dock 中的图像并查看不同的窗口，当我这样做时，要么什么都没有发生，要么一切都冻结了。每次打开 Thunderbird 时，它的布局也不同。无论我从 Dock 还是终端打开它，情况都一样。我甚至不知道从哪里开始寻找，也不知道我要寻找什么才能让它正常工作。我有 Ubuntu 21.10，Thunderbird 91.5.0。
在终端中我收到多条错误消息，但不知道如何解释这些消息。
