无法导航到身份注销页面 -ASP.Net Core 3.1-

如何解决无法导航到身份注销页面 -ASP.Net Core 3.1-

我一直在扩展和修改 IdentityUser 类，并进行了相应的 EntityFramework 迁移调整，数据库反映了更改，然后我启动了站点。我发现之前提到 IdentityUser 的所有地方都必须更改为新的 User 类（IdentityUser 的子类）。我进行了一些更改，需要对 Startup.cs 文件进行一些调整。现在我可以登录但无法注销。似乎我的网站已被完全锁定在“身份”区域中生成的 Razor 页面之外。所以，这是我的 Startup.cs 页面，也许那里有问题。

也许你有一些奇怪的想法，让访问剃刀页面就这样停止！非常感谢任何建议。
