Code Issues in C Chained List

Question

I’m having a problem with a C code. I’m trying to open a txt file that has movie name, year , actor,... And I’m putting the movies on a chained list. The problem is at the time of sorting the movies in the list, I tried to do by the bubble method (Bubble Sort) only that as the list is very large, when running in Dev the program is running infinitely the function without executing the rest that is in the main (by the inefficiency of sorting) someone would have a hint or help for me to apply in the code and be able to sort the list?

Follows the code:

 #include<stdio.h>
 #include<stdlib.h>
 #include<string.h>
 #include<conio.h>
  #define N 10000

 //wt escrita
  //rt leitura

 typedef struct Lista
 {
 char data[N];
 struct Lista *next;
 }Filmes;

 typedef struct ListaDupla 
{
char pessoa[N];
struct ListaDupla *prox;
struct ListaDupla *ant;
}DuplaLista;

  struct Lista* Insert(struct Lista *head,char data[N])
  {
    char aux3[N];
  struct Lista* tmp=((struct Lista*)malloc(sizeof(struct Lista)));
 int aux5;
 strcpy(tmp->data,data);
    tmp->next=NULL;
 if(head==NULL)
 {

    head=tmp;
    return head;
 }else{

struct Lista* aux=head;
struct Lista* aux2=head;
    while(aux->next!=NULL){
        aux=aux->next;
    }

    aux->next=tmp;



    while(aux!=NULL)
    {

        aux2=aux2->next;
        while(aux2!=NULL)
        {
     aux5=strcmp(aux->data,aux2->data);
    if(aux5>0)
    {

        strcpy(aux3,aux->data);
        strcpy(aux->data,aux2->data);
        strcpy(aux2->data,aux3);    
    }
        }
        aux=aux->next;
    }





    return head;
  } 

  // Complete this method
  }

 int main()
 {
 struct Lista* filmes=((struct Lista*)malloc(sizeof(struct Lista)));
 int opcao;
 char aux2[N];
 FILE *arq;
arq=fopen("nomes.txt","rt");
int i,a=0,b,aux;
char linha[600],nome[100];
if(arq==NULL)
{
    printf("Ocorreu um erro!");
    return 1;
}


  while(fgets(linha,700,arq))
  {



char *p=strtok(linha,",");
filmes=Insert(filmes,p);
while(filmes->next!=NULL)

{

printf(" \n Nome:%s",filmes->data);
filmes=filmes->next;
 }











    }



    fclose(arq);

  }
