Blazor WebAssembly stuck on Loading... when configuring dependency injection for a class library

So I built a class library that I will use for various different projects in the future. Now when I want to implement it and set the options in my Program.cs file, my blazor app gets stuck on the Loading... page. I can't seem to find the problem or why this is occuring.

In my class library I have a model ConfigurationSettings and a class with a method to set the configuration settings.

 public class ConfigurationSettings
{
    public string ConnectionString { get; set; }
    public string Token { get; set; }
    public string Issuer { get; set; }
    public string Audience { get; set; }
}
 public static class ServiceCollectionExtensions
{
    public static IServiceCollection AddLibrary(this IServiceCollection services, Action<ConfigurationSettings> configure)
    {
        services.Configure(configure);        
        services.AddDbContext<ApplicationDbContext>((provider, options) =>
        {
            var myLibraryOptions = provider.GetRequiredService<IOptions<ConfigurationSettings>>().Value;
            options.UseSqlServer(myLibraryOptions.ConnectionString);
        });

        return services;
    }
}

This configurationSettings will come from the main application implementing this class library.

In my Blazor Web Assembly application, I added the following to set the configurationSettings->

 builder.Services.AddLibrary(options =>
{
    options.ConnectionString = connectionString;

    IConfigurationSection configurationSettingsSection = builder.Configuration.GetSection("ConfigurationSettings");
    options.Token = configurationSettingsSection["Token"];
    options.Issuer = configurationSettingsSection["Issuer"];
    options.Audience = configurationSettingsSection["Audience"];
});
builder.Services.AddScoped<IAuthService, AuthService>();

Any suggestions on what I can possibly do to test and solve this issue as when I remove the above from my Program.cs everything works without issues.
