Consumer does not consume messages

This is my mass transit configuration in Program.cs:

    builder.Services.AddMassTransit(x =>
    {
        x.UsingRabbitMq((context,cfg) =>
        {
            cfg.Message<IOrder>(f => f.SetEntityName("new-order"));
            cfg.ReceiveEndpoint("new-order", f => 
            {
                f.Consumer<ConsumeNewOrder>();
            });
        });
    });

   builder.Services.AddHostedService<Worker>();

Background service, which publishes new messages in a new-order queue:

    public class Worker : BackgroundService
    {
        readonly IBus _bus;
        public Worker(IBus bus)
        {
            _bus = bus;
        }

        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while(!stoppingToken.IsCancellationRequested)
            {
                await _bus.Publish<IOrder>(new { Id = 2 },
                    stoppingToken);
                await Task.Delay(3000, stoppingToken);
            }
        }
    }

Consumer:

public class ConsumeNewOrder : IConsumer<IOrder>
{
    public async Task Consume(ConsumeContext<IOrder> context)
    {
        // do stuff
    }
}

Everything works locally in this project, but if I will split this code in 2 projects (copy IOrder and move consumer), it will not work, because consumer wont receive messages, but there will be new-order_skipped exchange and queue. The _skipped queue appears because consumer does not consume messages, but I don't know why. Please help
