flutter - Flutter 找不到设备。AndroidStudio 内部也是如此。“adb 没有响应”但杀死任务无济于事。颤振医生抛出异常

Question

我同时使用 Windows 10 和 MacOS 10.13.6

两台机器上都开始出现同样的问题，我认为我没有进行任何引发问题的更改。它只是在 12 小时内在 Win 10 和 MacOS 上自发崩溃。

运行AndroidStudio，设备下拉不会显示插入Android手机，然后设备下拉消失。这发生在两个平台上。

颤振运行也因“adb 无响应”而失败我已经使用任务管理器、adb kill-server、taskkill /F /IM adb*、killall adb 杀死了 adb，并使用 adb 设备重新启动它。adb devices 输出看起来不错：

$ adb devices
List of devices attached

即使设备已连接。

更新：Mac 可与 Android 模拟器配合使用。

莫名其妙地，在几次重新启动后，它又开始工作了。有谁知道是什么原因造成的？
