urlpatterns = [
    path('', views.dashboard, name="dashboard"),
    path('entrar/', LoginView.as_view(template_name='usuarios/login.html'), name="login"),
    path('saida/', LogoutView.as_view(), {'next_page':'core_home'}, name="logout"),
    path('cadastre-se/', views.register, name="register"),
    path('nova-senha/', views.password_reset, name="password_reset"),
    path('confirmar-nova-senha/(?P<key>\w+)/$', views.password_reset_confirm, name="password_reset_confirm"),
    path('editar/', views.edit, name="edit"),
    path('editar-senha/', views.edit_password, name="password"),
]

form py.

class PasswordResetForm(forms.Form):

    nrg = forms.CharField(label='RG')

    def clean_nrg(self):
        nrg = self.cleaned_data['nrg']
        if User.objects.filter(nrg=nrg).exists():
            return nrg
        raise forms.ValidationError(
            'Nenhum usuário encontrado com esse RG'
        )

        context['success'] = True
        return redirect('usuarios:password_reset_confirm')

    return render(request, template_name, context)


def password_reset_confirm(request, key):
    template_name = 'usuarios/password_reset_confirm.html'

Okay, I’ll rework the code, just what I needed to change, so you can update yours with the issues solved. You may have to change the order also the route that I enclose below, I had to put it before the 'password_reset_confirm'.

py.

...
path('confirmar-nova-senha/(?P<key>\w+)', app.views.password_reset_confirm, name="password_reset_confirm"),
path('nova-senha/', app.views.password_reset, name="password_reset"),
...

py views.

# '''
# funcao para alterar senha na tela de login,
# com o usuario fora do sistema sem logar
# '''
def password_reset(request):
    template_name = 'usuarios/password_reset.html'
    if request.method == 'POST':
        form = PasswordResetForm(request.POST or None)
        if form.is_valid():
            user = form.save()
            return redirect('password_reset_confirm', key=user.key)
    else:
        form = PasswordResetForm()
    return render(request, template_name, { 'form': form })


# '''
# funcao para resetar senha
# com o usuario fora do sistema sem logar
# '''
def password_reset_confirm(request, key):
    template_name = 'usuarios/password_reset_confirm.html'
    context = {}
    reset = PasswordReset.objects.get(key=key, confirmed=False)
    if request.method == 'POST':
        form = SetPasswordForm(user=reset.user, data=request.POST or None)
        if form.is_valid():
            form.save()
            reset.confirmed = True
            reset.save()
            context['success'] = True
            return redirect('login')
    else:
        context['form'] = SetPasswordForm(user=reset.user)
        context['key'] = reset.key 
    return render(request, template_name, context)

Forms.py

class PasswordResetForm(forms.Form):

    nrg = forms.CharField(label='RG')

    def clean_nrg(self):
        nrg = self.cleaned_data['nrg']
        if User.objects.filter(nrg=nrg).exists():
            return nrg
        raise forms.ValidationError(
            'Nenhum usuário encontrado com esse RG'
        )

    def save(self):
         user = User.objects.get(nrg=self.cleaned_data['nrg'])
         key = generate_hash_key(user.username)
         reset = PasswordReset(key=key, user=user)
         reset.save()
         return reset
