我正在使用 Ionic Angular 和 Capacitor 构建一个应用程序。 根据 Capacitor 的文档，他们从 5.0 版本开始支持 Android：
Android 版本对 Capacitor 的支持比 iOS 更复杂。目前，我们的目标是 API 级别 21 或更高版本，即 Android 5.0 (Lollipop) 或更高版本。这代表了超过 90% 的 Android 市场。
但是当我尝试在真实设备上启动 Android 6.0.1 Marshmallow 中的应用程序（而不是我知道使用非常旧的 WebView 的模拟器）时，我从 Logcat 收到此错误：

我已经尝试使用多个 browserslistrc 配置并将 tsconfig.ts 中的目标设置为 es2015，但没有任何效果。

我真的需要在 Android 6 上运行这个应用程序，因为这个应用程序需要经过 Meta 的审核过程才能使用一些 Facebook/Instagram 数据，并且他们正在 Android 6 Marshmallow 设备上进行测试，但只要出现此错误，应用程序将显示启动画面，然后只显示白屏。
我在不同旧 Android 版本的模拟器中遇到了这个问题。解决方案是通过 Google Play 更新 Chrome 和 System Webview，以使应用程序再次正常启动。项目方面我不需要做任何改变。
