错误：当前项目不支持运行配置应用程序。无法获取应用ID

每次我在 Android Studio 中打开项目时，都会出现此错误：

Error: Run configuration app is not supported in the current project. Cannot obtain the application ID.

当我点击Sync project with Gradle Files，同步过程后，此错误消失。However当我重新打开项目或重新启动Android Studio时，再次出现此错误。

I know Sync project with Gradle Files可以做到这一点，但我不想每次打开项目时都这样做，我尝试降级 Android Studio，但它似乎不起作用。

我的环境：

• Android Studio 海豚 | 2021年3月1日
• 摇篮7.5.1
• Android Gradle 插件 7.3.0

有趣的是，每次启动 Android Studio 时，都会弹出 IDE 错误：

我依赖于我自己编写的另一个私有模块设置.gradle

includeBuild('external/xxxx-xxxx') {
    name "xxxx-xxxx"
    dependencySubstitution {
        substitute module('com.xxxx.xxxx:xxxx:1.0.0') using project(':xxxx-xxxx')
    }
}

也许是我的子模块的问题或者 Android Studio/Gradle 中的错误？其他项目没有这个问题。

就我而言，清单文件中缺少包名称（很奇怪，因为我刚刚创建了项目，默认情况下它应该在那里），但我添加了它，现在它正在工作。
