尝试到达“管理/索引”时发生未处理的异常（使用脚手架用户）

我有点迷茫，我遵循了Microsoft教程（https://docs.microsoft.com/en-us/aspnet/core/security/authentication/add-user-data?view=aspnetcore-2.2&tabs= netcore-cli）来修改User表（添加了几列）。 此后，当我单击“注册”或尝试访问“管理/索引”时出现错误。

所以我删除了所有修改后的代码以重新开始（我想我没有忘记任何东西）。

我还完全删除了包含迁移的文件夹，然后在PM中运行以下命令：Drop-Database -Context ApplicationDbContext 随后：Add-Migration FirstMig

从那时起，我的数据库已被完全重新创建，我终于可以访问“注册”页面。

根据缺点，仍然无法访问“管理/索引”。 我做了很多研究，但找不到解决方法。

这是错误，请随时告诉我是否需要一段代码：

An unhandled exception occurred while processing the request.
