【问题描述】：
我使用 Visual Studio 2019 安装了 Android 模拟器，并使用 Windows 功能启用了 hyper-v 和 hypervisor 平台。
我使用“Android 设备管理器”工具创建了新设备，当我启动它时，它运行良好。但是，如果我关闭它并重新开始，它会打开并且屏幕显示上次会话的最后状态。然后什么也没有发生，它永远不会加载。如果我将设备系统设置降至默认状态并重新启动，它会起作用，但我不想每次都这样做，而且我希望能够在会话之间存储应用数据。
那么我该如何让它发挥作用呢？
或者我如何让它停止尝试保存状态，总是冷启动？
我有 Windows 10，Android 模拟器版本 28.0.25，SDK 工具 26.1.1，SDK 平台工具 28.0.2。
我的设备的 config.ini：
