Azure AD B2C login redirect not working in Blazor WASM Standalone

I just started a new Blazor WASM Standalone project (targeting .NET 9) using the Blazor Bootstrap starter template here.

I then went through the setup process to use Azure AD B2C following this document here.

It detects that I'm not yet logged in and displays the correct message but when I click on Login link, it does nothing. I do see that the URL correctly changes to /authentication/login in the browser address bar but the actual redirect doesn't happen.

The interesting thing is that I also started a sepearate vanilla Blazor WASM Standalone project and using the same exact files/settings, I got that to work fine. Clicking login opens up the popup and I'm able to login just fine. Everything is identical except for Blazor Bootstrap template that I'm using in my original project.

I found this potential solution but it doesn't fix the problem for me i.e. adding the following to the project file didn't work.

<ItemGroup><TrimmerRootAssembly Include="Microsoft.AspNetCore.Components.WebAssembly.Authentication" /></ItemGroup>

Here's my App.razor file:

<CascadingAuthenticationState><Router AppAssembly="@typeof(App).Assembly"><Found Context="routeData"><AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)"><NotAuthorized>                    @if (context.User.Identity?.IsAuthenticated != true)                    {<RedirectToLogin />                    }                    else                    {<p role="alert">You are not authorized to access this resource.</p>                    }</NotAuthorized></AuthorizeRouteView><FocusOnNavigate RouteData="@routeData" Selector="h1" /></Found><NotFound><PageTitle>Not found</PageTitle><LayoutView Layout="@typeof(MainLayout)"><p role="alert">Sorry, there's nothing at this address.</p></LayoutView></NotFound></Router></CascadingAuthenticationState>

And here's my Program.cs:

using MyApp;using Microsoft.AspNetCore.Components.Web;using Microsoft.AspNetCore.Components.WebAssembly.Authentication;using Microsoft.AspNetCore.Components.WebAssembly.Hosting;bool _isProduction = true;string _baseApiUrl = _isProduction ? "https://{MY_APP_PRODUCTION_URL}" : "https://localhost:7141";var builder = WebAssemblyHostBuilder.CreateDefault(args);builder.RootComponents.Add<App>("#app");builder.RootComponents.Add<HeadOutlet>("head::after");// Add Azure AD B2C authenticationbuilder.Services.AddMsalAuthentication(options =>{    builder.Configuration.Bind("AzureAdB2C", options.ProviderOptions.Authentication);    options.ProviderOptions.DefaultAccessTokenScopes.Add("https://{MY_B2C_TENANT_DOMAIN}.onmicrosoft.com/api/{MY_CUSTOM_SCOPES}");});// Add HttpClient for MyApp API callsbuilder.Services.AddHttpClient("MyAppApiClient",        client => client.BaseAddress = new Uri(_baseApiUrl))    .AddHttpMessageHandler(sp =>    {        var handler = sp.GetService<AuthorizationMessageHandler>()        .ConfigureHandler(             authorizedUrls: new[] { _baseApiUrl },             scopes: new[] { "openid", "profile", "offline_access", "https://{MY_B2C_TENANT_DOMAIN}.onmicrosoft.com/api/{MY_CUSTOM_SCOPES}" }         );        return handler;    });builder.Services.AddScoped(sp => sp.GetRequiredService<IHttpClientFactory>()    .CreateClient("MyAppApiClient"));builder.Services.AddBlazorBootstrap();await builder.Build().RunAsync();

Any idea what maybe the issue here? I'd appreciate some suggestions. Thank you!
