Assign custom role to user

Question

I am a beginner in django and trying to create a web application for my task. I am trying to assign a roles to every to user. But i have an error. enter image description here

My model

 class Rol(Group):

   state = models.BooleanField(default=True)
   description = models.CharField(max_length=200)
   permission = models.ManyToManyField(Permission)

   def __str__ (self):
       return '{}'.format(self.state,self.description, self.permission)

In this part i don't have any problem the permission is asigned to rol

But here My model:

  class User(AbstractUser):
      state = models.BooleanField(default=True)
      roles = models.ManyToManyField(Rol)
    def __str__ (self):
       return '{}'.format(self.username,self.state,self.roles)

My form:

 class UserForm(UserCreationForm):
    username = forms.CharField(label="User",widget=forms.TextInput(attrs= 
    {"class":"form-control"}))
    password1 = forms.PasswordInput()
    password2 = forms.PasswordInput()
    state = forms.CheckboxInput()
    roles =forms.ModelMultipleChoiceField(label="Roles",queryset=Group.objects.all(),
    widget=forms.CheckboxSelectMultiple)

   class Meta:
       model = User

    fields = [
        "username",
        "password1",
        "password2",
        "activo",
        "roles"
        ]

In roles lists the roles created but not assigned to the user at the time of saving, it shows me an error:

Field 'id' expected a number but got .
The above exception (int() argument must be a string, a bytes-like object or a real number, not 'Group') was the direct cause of the following exception:

And highlight this line

form.save_m2m()

My view

  def create_user(request):
     if request.method == 'POST':
       form = UserForm(request.POST)
       if form.is_valid():
         form2=form.save(commit=False)
         form2.save()
         form.save_m2m()
       return redirect('list_user')
      return render(request, 'user/user_form.html',{'form': form})
     else:
      form = UserForm()
     return render(request, 'user/user_form.html',{'form': form})

OBS: But in my user form when changing the queryset of roles: Group by Rol, it assigns the roles but it does not list the names, only the states
