Disabling multi-tenancy cause GetCurrentLoginInformationsOutput.User.get returned null

I am using ASP.NET MVC 5.X (Multi page and EF) to generate a solution, add some tables and entities, and then disable code first, at this time, things work.

Then I disable multi tenancy, but remove below line:

Configuration.MultiTenancy.IsEnabled = NxShufWebConsts.MultiTenancyEnabled;

Click F5, an exception (NullReferenceException) hit in the first line of GetShownLoginName method in SideBarUserAreaViewModel.cs file.

It says GetCurrentLoginInformationsOutput.User.get returne null.

Some callstack is as following:

ERROR 2018-08-10 23:39:14,217 [7    ] NxShufWeb.Web.Controllers.HomeController - 执行处理程序“System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper”的子请求时出错。

   在 System.Web.Mvc.BuildManagerCompiledView.Render(ViewContext viewContext, TextWriter writer)

Note: Because I disabled the code first, and delete the migration table, I did not run Update-Database again.

Any help?
