IAsyncEnumerable cannot be used for parameter of type IEnumerable - entity-framework-core

Question

I have entities, service and view models. I use the service models in the services and in the service I map from entity to the service model and I return IQueryable<UserServiceModel> and I use the service in the controller but when I try to materialize the result and map it to the view model with Select it throw exception:
ArgumentException: Expression of type 'System.Collections.Generic.IAsyncEnumerable1[TestDriveServiceModel]' cannot be used for parameter of type 'System.Collections.Generic.IEnumerable1[TestDriveServiceModel]' of method 'System.Collections.Generic.List1[TestDriveServiceModel] ToList[TestDriveServiceModel](System.Collections.Generic.IEnumerable1[TestDriveServiceModel])'
Parameter name: arg0
// the service map from entities to service models and returns them
// userServiceModels is the result of the service
// Here the error is thrown
var viewModel = await userServiceModels.Select(usm => new UserViewModel()
{
TestDrivesCount = usm.TestDrives.Count()
}).ToListAsync();
