AddAutoMapper / ConstructServicesUsing not working

I'm using AutoMapper 10.1.1, because this is the last version with .NET Framework support. And I am using Microsoft dependency injection.

I have a type converter I want constructed using dependency injection (it refers to a cache repo in memory).

If I use this code, it does not work.

var services = new ServiceCollection()
    ...
    .AddAutoMapper((sp, cfg) =>
    {
        cfg.ConstructServicesUsing(t => ActivatorUtilities.GetServiceOrCreateInstance(sp, t));
        cfg.AddProfiles();
    }, Array.Empty()) // <-- to disambiguate the calls if nothing is provided
    .BuildServiceProvider();

mMapper = services.GetRequiredService();

This, on the contrary, does work.

var services = new ServiceCollection()
    ...
    .BuildServiceProvider();

var config = new MapperConfiguration(cfg =>
{
    cfg.ConstructServicesUsing(t => ActivatorUtilities.GetServiceOrCreateInstance(services, t));
    cfg.AddProfiles();
});

mMapper = config.CreateMapper();

By not working I mean that there is an exception that it cannot construct my type converter. It seems that ConstructServicesUsing is simply ignore, because even inserting a throw statement there does not change the outcome.

To be able to inject IMapper I would really like to use the second version. What do I do wrong?
