科特林 || Room DB：计算数据库实时数据时出现异常

Question

我有这个带有 Room DB 和 API 的应用程序。 API 中的一些常用数据与每个用户的会话一起存储在 Room DB 中 但在这里，尽管清除了缓存、清除了设备上应用程序的数据、使 Android studio 上的缓存无效、清理了构建和重建，但我还是遇到了这个异常。

如果从设备上卸载应用程序，则应清除房间数据库数据，并且不应在下次安装应用程序时从上次登录的用户帐户开始。默认情况下，应用程序流程为 OnBoarding > 登录屏幕 > 主屏幕 但在此例外情况下，新安装的应用程序会使用上次（卸载应用程序之前）登录的相同帐户凭据直接进入主屏幕。一两秒后，主屏幕会因此异常而崩溃。

您是否将版本号升级为数据库邮政编码更改，我建议从它开始
