CryptographicException: 在加密操作期间发生错误 : 如何自动修复它？

这是我的Global.ascx.cs文件，其中包含FormsAuthentication：

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
    protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
    {
        HttpCookie authCookie = Request.Cookies["CookieFA"];
        if (authCookie != null)
        {
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
            CustomPrincipal principal = new CustomPrincipal(authTicket.Name);
            CustomPrincipalSerializeModel userSerializeModel = JsonConvert.DeserializeObject(authTicket.UserData);
            principal.UserID = userSerializeModel.ID;
            principal.FirstName = userSerializeModel.FirstName;
            principal.LastName = userSerializeModel.LastName;
            principal.Roles = userSerializeModel.RoleName.ToArray();
            HttpContext.Current.User = principal;
        }
    }
    protected void Application_Error(object sender, EventArgs e)
    {
        Exception exception = Server.GetLastError();
        if (exception is CryptographicException)
        {
            FormsAuthentication.SignOut();
            Session.Abandon();
            // 清除身份验证 cookie
            HttpCookie cookie1 = new HttpCookie("CookieFA", "");
            cookie1.Expires = DateTime.Now.AddYears(-1);
            Response.Cookies.Add(cookie1);
            // 清除会话 cookie（对于当前问题不是必需的，但我建议您仍然这样做）
            SessionStateSection sessionStateSection = (SessionStateSection)WebConfigurationManager.GetSection("system.web/sessionState");
            HttpCookie cookie2 = new HttpCookie(sessionStateSection.CookieName, "");
            cookie2.Expires = DateTime.Now.AddYears(-1);
            Response.Cookies.Add(cookie2);
            FormsAuthentication.RedirectToLoginPage();
        }
    }
}

但是即使有了Application_Error方法，我经常遇到这个错误：

[CryptographicException: 在进行加密操作期间发生错误。]
   System.Web.Security.Cryptography.HomogenizingCryptoServiceWrapper.HomogenizeErrors(Func`2 func, Byte[] input) +115
   System.Web.Security.Cryptography.HomogenizingCryptoServiceWrapper.Unprotect(Byte[] protectedData) +70
   System.Web.Security.FormsAuthentication.Decrypt(String encryptedTicket) +9778338
   GPMS.MvcApplication.Application_PostAuthenticateRequest(Object sender, EventArgs e) in C:\repos\GPMS\GPMS\Global.asax.cs:32
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +141
   System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) +48
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +71

已经尝试了一些写在这里建议的解决方法，但无法解决问题。

我没有使用Azure。我不想使用“删除 cookie 就一切正常”的解决方案：无法强制用户删除 cookie。系统必须自动执行此操作。

我应该在哪里修复它？也许我在全局错误处理程序中遗漏了一些东西？

看起来Application_Error可能没有被调用？
