在过去的几天里，我使用 Selenium WebDriver 运行测试没有任何问题。但是，即使我没有更改代码或系统中的任何内容，但最近几次尝试创建新的浏览器会话时，我总是收到以下错误： Link
无论我是尝试通过代码还是通过浏览器手动创建会话，都会发生这种情况。
这是运行 Selenium 服务器和三个测试的结果：

我试过降级，重新安装所有东西，但似乎没有任何效果。
我正在使用什么：
- Ubuntu 18.04
- Selenium Java 服务器 3.9.1
- 铬 73
- 铬驱动程序 74
此外，奇怪的是，我的同事和我同样在 Selenium 上工作，现在在他们自己的系统上遇到了完全相同的问题。
