刚刚在 Mac 上更新到 Android Studio 4.2.1，现在模拟器不再工作 [英] Just updated to Android Studio 4.2.1 on Mac and now emulator no longer works
问题描述
我刚刚将 Android Studio 更新到最新版本 4.2.1，模拟器停止工作.每次我尝试启动新的虚拟设备时，它都会崩溃，并且 AVD Manager 会显示此错误:
I just updated Android Studio to its latest version 4.2.1 and the emulator stopped working. Every time I try to launch a new virtual device it crashes and AVD Manager shows me this error:
AVD Pixel_C_API_30 的模拟器进程被杀死"
"The emulator process for AVD Pixel_C_API_30 was killed"
这是我迄今为止尝试过的:
Here is what I have tried so far:
冷启动重启.
Cold boot restart.
在 AVD 管理器中删除并重新创建了虚拟设备.
Deleted and recreated the virtual device inside AVD manager.
移除并重新安装模拟器 SDK 包(版本 30.7.4)
Removed and re-installed the emulator SDK package (version 30.7.4)
退出并重新启动 Android Studio 以及模拟器.
Quit and restarted Android Studio as well as the emulator.
从头开始创建一个新的虚拟设备.
Created a new virtual device from scratch.
尝试了几种不同的虚拟设备.
Tried several different virtual devices.
以上所有内容都给了我相同的确切结果:模拟器崩溃并且 AVD 管理器向我显示上述错误.
All of the above gives me the same exact result: the emulator crashes and AVD manager shows me the error above.
这是我从 MacOS 得到的错误(只是它的摘录):

有什么想法吗?我在 MacOS 10.15.6，Android Studio 版本 4.2.1，运行时版本:11.0.8+10-b944.6916264 x86_64
Any ideas? I am on MacOS 10.15.6, Android Studio version 4.2.1, Runtime version: 11.0.8+10-b944.6916264 x86_64
更新:我尝试像这样从终端启动它:
Update: I tried to launch it from the terminal like this:
./emulator -avd Pixel_C_API_30
在它崩溃之前我得到了以下输出:
And I got the following output right before its crash:

推荐答案
所有的答案都太混乱了，无法理解.更换 SDK 或升级操作系统.我发现最快的方法是:
All of the answers are too confusing to follow. Replace SDK or upgrade OS. The quickest way I found is to:
工具 >SDK 管理器 >SDK工具
Tools > SDK Manager > SDK Tools
取消选择 Android Emulator，然后单击应用.- Android 模拟器将被删除.
De-select Android Emulator, then click Apply. - The Android Emulator will be deleted.
现在，默认情况下显示的模拟器版本为 30.6.5.选中复选框并单击应用.将安装此版本的模拟器.
Now, by default the Emulator version shown will be 30.6.5. Select the checkbox and click apply. This version of emulator will be installed.
就是这样，只需要你 2 分钟的时间.
That is it, just 2 minutes of you time.
更新:2021 年 7 月 1 日使用最新的模拟器版本 30.7.5 解决了问题
Update: 1 Jul 2021 Issue solved with latest Emulator version 30.7.5
