Flutter VS Code Emulator 卡在运行 Gradle 任务“assembleDebug”上

Question

从昨天晚上开始，我一直无法在模拟器中打开我的应用程序。到那时为止一切都很好。

Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
√  Built build\app\outputs\flutter-apk\app-debug.apk.

通常需要大约 2 分钟才能打开，但它只是卡在那里大约 15 分钟。所以我寻找答案，第一个答案说使用 gradlew clean 和 gradlew build 。我这样做了，但仍然被卡住了，但又出现了另一个错误。

Launching lib\main.dart on Android SDK built for x86 in debug mode...
lib\main.dart:1
Note: C:\flutter\.pub-cache\hosted\pub.dartlang.org\path_provider_android-2.0.12\android\src\main\java\io\flutter\plugins\pathprovider\PathProviderPlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
√  Built build\app\outputs\flutter-apk\app-debug.apk.

然后我尝试了这里类似问题的答案，建议进行flutter pub缓存修复。还是没有运气。

然后我尝试了这里答案中的另一个建议来升级颤振。从那以后我已经几个月没有升级flutter了，所以我这样做了，但问题仍然存在。

我从这里的一个问题的评论中读到，当他们在终端中使用 flutter run -v 运行项目时，它在大约 20 分钟后打开。所以我开始了它，因为我的笔记本电脑已经用了 6 年了，运行的是第 6 代 i5 和 8GB 内存，我认为可能需要更长的时间。所以我把它留在那里，现在大约 2 小时后我的终端卡在：

我达到了问题字符限制，所以我将终端的输出输入 在线记事本：https://anotepad.com/notes/3jri4gpc

我刚刚关闭了模拟器，终端将其添加到上面的

From [+7331895 ms] waiting: 在关闭模拟器后的第一行中，我可以看到它运行了大约 122 分钟。

我不明白这里出了什么问题。为什么模拟器突然停止正常工作？

如何让它发挥作用以便我可以继续我的应用程序开发？请帮忙。
