        public Startup(IConfiguration configuration)  
        {  
            Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(configuration).CreateLogger();  
            Configuration = configuration;  
  
            IConfigurationBuilder builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json");  
            configRoot = builder.Build();  
  
            AppSettings = new AppSettings();  
            Configuration.Bind(AppSettings);  
        }  
  
        public IConfiguration Configuration { get; }  
  
        public void ConfigureServices(IServiceCollection services)  
        {  
            services.AddController();  
  
            services.AddDbContext(Configuration, configRoot);  
  
            services.AddIdentityService(Configuration);  
  
            services.AddAutoMapper();  
  
            services.AddScopedServices();  
  
            services.AddTransientServices();  
  
            services.AddSwaggerOpenAPI();  
  
            services.AddMailSetting(Configuration);  
  
            services.AddServiceLayer();  
  
            services.AddVersion();  
  
            services.AddHealthCheck(AppSettings, Configuration);  
  
            services.AddFeatureManagement();  
        }  
  
  
  
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory log)  
        {  
            if (env.IsDevelopment())  
            {  
                app.UseDeveloperExceptionPage();  
            }  
  
            app.UseCors(options =>  
                 options.WithOrigins("http://localhost:3000")  
                 .AllowAnyHeader()  
                 .AllowAnyMethod());  
  
            app.ConfigureCustomExceptionMiddleware();  
  
            log.AddSerilog();  
  
            //app.ConfigureHealthCheck();  
  
  
            app.UseRouting();  
  
            app.UseAuthentication();  
  
            app.UseAuthorization();  
            app.ConfigureSwagger();  
            app.UseHealthChecks("/healthz", new HealthCheckOptions  
            {  
                Predicate = _ => true,  
                ResponseWriter = UIResponseWriter.WriteHealthCheckUIResponse,  
                ResultStatusCodes =  
                {  
                    [HealthStatus.Healthy] = StatusCodes.Status200OK,  
                    [HealthStatus.Degraded] = StatusCodes.Status500InternalServerError,  
                    [HealthStatus.Unhealthy] = StatusCodes.Status503ServiceUnavailable,  
                },  
            }).UseHealthChecksUI(setup =>  
              {  
                  setup.ApiPath = "/healthcheck";  
                  setup.UIPath = "/healthcheck-ui";  
                  //setup.AddCustomStylesheet("Customization/custom.css");  
              });  
  
  
            app.UseEndpoints(endpoints =>  
            {  
                endpoints.MapControllers();  
            });  
        }  
    }  
  
  
  
   
  

  
and his code as following

peogram.cs .net core 6

using HealthChecks.UI.Client;  
using Microsoft.AspNetCore.Diagnostics.HealthChecks;  
using Microsoft.EntityFrameworkCore.Infrastructure;  
using Microsoft.Extensions.Diagnostics.HealthChecks;  
using static Microsoft.EntityFrameworkCore.DbLoggerCategory;  
//using static Microsoft.EntityFrameworkCore.DbLoggerCategory;  
  
  
var builder = WebApplication.CreateBuilder(args);  
  
// Add services to the container.  
builder.Services.AddRazorPages();  
var app = builder.Build();  
  
  
if (!app.Environment.IsDevelopment())  
{  
    app.UseExceptionHandler("/Error");  
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.  
    app.UseHsts();  
}  
  
app.UseHttpsRedirection();  
app.UseStaticFiles();  
app.UseRouting();  
  
app.UseAuthorization();  
  
  
  
  
app.UseEndpoints(endpoints =>  
{  
    endpoints.MapControllers();  
});  
  
app.MapRazorPages();  
  
app.Run();

Answer

Move services.* to after line 12 before line 13 (use builder.Services instead of services) The config where you need it (builder.Configuration)
.

Then the required middleware registration in the proper order. You should read the updates as much of the middleware has changed, especially endpoint routing.
