Unable to determine the relationship represented by navigation 'UserAddress.CreatedBy

Question

I get the error on the title when trying to run a query in the Context.

The related entities are as follow:

public abstract class Entity : IEntity
{
    public abstract Guid Id { get; set; }

    public DateTime DateCreated { get; set; }
    public DateTime? DateDeleted { get; set; }
    public DateTime LastModified { get; set; }

    [ForeignKey("CreatedById")]
    public virtual User CreatedBy { get; set; }
    [ForeignKey("LastModifiedById")]
    public virtual User LastModifiedBy { get; set; }
    [ForeignKey("DeletedById")]
    public virtual User DeletedBy { get; set; }

    public Guid? CreatedById { get; set; }
    public Guid? LastModifiedById { get; set; }
    public Guid? DeletedById { get; set; }
}

public class User : Entity
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public override Guid Id { get; set; }

    [MaxLength(255)]
    public string Alias { get; set; }

    [MaxLength(255)]
    public string WindowsUserName { get; set; }

    [NotMapped]
    public byte VersionMajor { get; set; } = 0;
    [NotMapped]
    public byte VersionMinor { get; set; } = 0;

    public DateTime? LastAccess { get; set; }
    public string LastIP { get; set; }

    public byte AvailableRestorations { get; set; }
    public byte AuthForms { get; set; }
    public DateTime? DeathDate { get; set; }
    public DateTime? LastDownloaderCheck { get; set; }
    public DateTime? LastUpdate { get; set; }

    #region NProps
    public virtual ICollection<UserAddress> UserAddresses { get; set; }
    #endregion
}

public class UserAddress : Entity
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public override Guid Id { get; set; }

    [MaxLength(6)]
    public byte[] MacAddress { get; set; }
    public string IP { get; set; }

    public DateTime? LastUse { get; set; }

    #region NProps
    [ForeignKey("UserId")]
    public virtual User User { get; set; }
    #endregion

    #region FKs
    public virtual Guid UserId { get; set; }
    #endregion
}

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<UserAddress>()
            .HasOne(e => e.User)
            .WithMany(e => e.UserAddresses)
            .HasForeignKey(e => e.UserId);
    }

All my entities inherit from the abstract Entity class.

This was working normally with Entity Framework 6. As I upgraded to EF-Core 6.0.2, I have throws from queries.
