解决方案：1. 询问了国际友人

，他建议勾选 development，结果并没什么用.

2. 老方法，剔除插件。搞了几个小时，最后找到是 besthttp 所导致，我升级besthttp2_2.6.3，正常工作。
一共花了一天。
不管是堆栈信息抓包也没法定位。只知道UnityWebRequestAssetBundle.GetAssetBundle(url) 就出错。只能一步一步的排查。
排查方法》创建一个空项目，把老项目的插件全部导入，不导入代码。在编写一个简单代码（UnityWebRequestAssetBundle.GetAssetBundle(url)）测试。  这样比在老项目中排查不知道快了多少倍。
