Authorize without identity tables in ASP.NET core 3.1

I wrote my project with asp.net core 3.1
My tables are similar to the tables
Now, when I enter the main page after logging in and click on the relevant menu, it directs me to the login form. Login again and click on the relevant menu and then redirect me to the login form again and this cycle continues

My role table in this database: UserGroups
Access table: UserKeys
Role and user relationship table: UserGroupMembers
Role and Access Relationship Table: UserGroupKeys

        {
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(
                    Configuration.GetConnectionString("DefaultConnection")));

            services.AddDbContext<KMCPortalDbContext>(options =>
                  options.UseSqlServer(
                      Configuration.GetConnectionString("DefaultConnection")));

            services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                .AddCookie(options =>
                {
                    options.Cookie.HttpOnly = true;
                    options.ExpireTimeSpan = TimeSpan.FromMinutes(30);
                    options.LoginPath = "/Account/Login";
                    options.AccessDeniedPath = "/Account/AccessDenied";
                    options.SlidingExpiration = true;
                });


            services.AddAuthorization(options =>
                   options.AddPolicy("Upper-Admin",
                       policy => policy.RequireClaim("UserGroupKeys")));
 // Upper-Admin is the role defined in the UserGroups table and UserGroupKeys is the same as the role and access relationship table</small>


            services.AddControllersWithViews();
            services.AddRazorPages();
        }
