Expo SDK 50 WebView下载异常：Expo Go正常，Android APK打包后失败

近期将Expo项目从SDK 48升级至SDK 50后，原通过WebView实现的文档下载功能出现异常：

• Expo Go中测试时文档下载可正常完成
• 打包为Android APK后，API通信正常，但文档下载失败并提示错误信息

使用expo-web-browser模块实现的文档下载在Expo Go和打包后的应用中均可正常运行：

import * as WebBrowser from 'expo-web-browser';
WebBrowser.openBrowserAsync(webViewSource);

但原WebView方案在打包APK后仍无法正常下载，该问题仅出现在Android平台，无法定位根因，寻求解决。

已尝试的方案 #

• 替换为expo-web-browser模块实现下载，此方案可正常工作，但希望保留原WebView方案
