从0.61.4升级后，React Native 0.61.5应用程序不断停止

Question

我刚刚在带有Android模拟器的Win10平台上使用nodejs 12.16.0重建了一个react native 0.61.5应用程序。我以前的版本是RN 0.61.4，并且运行良好。我所做的升级是初始化一个React Native项目，并将模块一个接一个地添加到新项目中。问题是我的新应用程序成功启动react-native run-android后一直停止运行。这是模拟器上的消息：

这是日志输出。该视图最终以某种方式分离：

这是package.json文件：

}

我怀疑是升级的依赖模块导致崩溃，但我还没有找到。启动构建成功，并且捆绑器的使用率为100％。 android studio和模拟器​​已重新启动，问题是相同的。导致应用停止的问题可能是什么？

我注意到的一件事是，在重建过程中需要安装一些其他模块。其中之一是模块react-native-screens，在使用前需要额外的setup。为react-native-screens进行进一步设置后，该应用程序开始正常运行。
