Blazor, windows account and AzureAD/Microsoft Identity Platform login automatic? - blazor-server-side

Question

If I create a new Blazor server application, choose to use Microsoft Identity Platform and connect to our work.
When I run that application without any changes, my windowsaccount log in and my name/mailadress at work shows on top on screen.
I have an old project where I got this behavior before but last week the project doesn't logged in with my workaccount automatic anymore, I need to push login button and then my Blazor server app login in with my workaccount automatic.
What I know I haven't change any code that connect to AzureAD last week. What code is it in a fresh Blazor Server application that are configure with Microsoft Identity Platform that make an automatic login if you are logged in with a microsoft account on your computer?
My Program.cs that don't login automatic anymore.
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApp(builder.Configuration.GetSection("AzureAd"));
builder.Services.AddControllersWithViews()
.AddMicrosoftIdentityUI();
builder.Services.AddRazorPages();
builder.Services.AddAuthorization(options =>
{
// By default, all incoming requests will be authorized according to the default policy
//options.FallbackPolicy = options.DefaultPolicy;
options.AddPolicy("Admin", policy => policy.RequireClaim("role", "Admin"));
});
builder.Services.AddAutoMapper(typeof(Program));
builder.Services.AddDbContext<ApplicationDbContext>(options =>
{
options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection"));
}, ServiceLifetime.Transient);
builder.Services.AddServerSideBlazor()
.AddMicrosoftIdentityConsentHandler();
..
builder.Services.AddHttpClient();
builder.Services.AddHttpContextAccessor();
builder.Services.AddControllers();// Add support for API controllers
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
var app = builder.Build();
// Configure the HTTP request pipeline.
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.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "Blazor API V1");
});
}
app.UseDeveloperExceptionPage();
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.MapControllers();
app.MapBlazorHub();
app.MapFallbackToPage("/_Host");
app.Run();
