How to write and read a table hash in/from a file (FILE) in C?

Question

I am using fread and fwrite but there is an error of execution.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef struct pessoa{
   char nome[20];
   char cpf[10];
   struct pessoa* next;
}Pessoa;

typedef struct lista{
   Pessoa* head;
}lista;

typedef struct hash{
   int qtd,table_size;
   lista** itens;
}Hash;

void imprimirHash(Hash ha){
  int i;
  Pessoa* aux;
  printf("==========================\n");
  for(i=0;i<ha.table_size;i++){
    if(ha.itens[i]!=NULL){
        aux = ha.itens[i]->head;
        while(aux!=NULL){
            printf("Nome: %s\n",aux->nome);
            printf("Cpf: %s\n",aux->cpf);
            aux = aux->next;
        }
    }
    printf("\n");
  }
}

void lerPessoa(Pessoa* pes){
   printf("Digite o nome: ");
   scanf("%s",pes->nome);
   printf("Digite o cpf: ");
   scanf("%s",pes->cpf);
}

Hash* criaHash(int table_size){
   Hash* ha;
   ha = (Hash *)malloc(sizeof(Hash));
   if(ha){
    int i;
    ha->table_size = table_size;
