1、云开发，前期上线运行正常，近期突然出现无法访问云数据库，部分手机无法显示动态数据，部分手机出现白屏；真机调试发现反馈问题如下：

Error: errCode: -502005 database collection not exists | errMsg: [ResourceNotFound] Db or Table not exist. Please check your request, but if the problem cannot be solved, contact us.

2、数据库本身无问题，数据库权限无问题，小程序工具测试无问题，能够正常显示和调用云数据库数据；

3、环境设置正常，云函数环境设置正常。

弄了很久也看了很多网上材料，还是没有解决，求各路大侠指点！不胜感激！
