Blazor WASM application Hangs on MSAL Authentication

[Julien-Marpault]

.Net 5 & .Net 6

I have a Blazor Wasm using Azure AD Authentication

Program.cs

builder.Services.AddMsalAuthentication(options =>
{
    builder.Configuration.Bind("AzureAD", options);
});

appsettings.json

"AzureAD": {
    "ProviderOptions": {
      "Authentication": {
        "Authority": "https://login.microsoftonline.com/11111111-2222-3333-4444-555555555555",
        "ClientId": "11111111-2222-3333-4444-555555555555",
        "RedirectUri": "URL DE PROD",
        "PostLogoutRedirectUri": "URL DE PROD",
        "ValidateAuthority": true
      },
      "DefaultAccessTokenScopes": [
        "openid",
        "offline_access",
        "https://graph.microsoft.com/User.Read"
      ],
      "LoginMode": "redirect",
      "Cache": {
        "CacheLocation": "LocalStorage"
      }
    }
  }

When authenticating the application hangs on code reception:
