System.InvalidOperationException: 'No service for type 'Quartz.Spi.ITypeLoadHelper' has been registered.'

Hi,
we are running a asp.net core 3.1 application. where we added the following code:
public void ConfigureServices(IServiceCollection services)
{
...
services.AddQuartz(q =>
{
// handy when part of cluster or you want to otherwise identify multiple schedulers
q.SchedulerId = "Tunnel-Core-Scheduler";

            // we take this from appsettings.json, just show it's possible
             q.SchedulerName = "Tunnel Core Scheduler";
        });

        // ASP.NET Core hosting
        services.AddQuartzServer(options =>
        {
            // when shutting down we want jobs to complete gracefully
            options.WaitForJobsToComplete = true;
        });

}

When we start the project i get "System.InvalidOperationException: 'No service for type 'Quartz.Spi.ITypeLoadHelper' has been registered.'"

what i am doing wrong?

You are missing type loader registration, which is:

 q.UseSimpleTypeLoader();
