Problem rendering correctly the select2 with ajax in the boostrap stepper

I am using Laravel 10 and blade, the script in the modals works correctly for me but when I wanted to integrate it with the boostrap stepper it stopped working, it renders a select2 in a common way without making the ajax query.

Same with the select to show images in the options it stopped working.

This is the ajax script:

$('#customer').select2({
      
      //dropdownParent: $('#personal'),
      minimumInputLength: 1,
      preAjax,
      ajax: {
          url: urlSearch,
          type: 'POST',
          delay: 250,
          data: function (params) {
            console.log(($.trim(params.term)))
            console.log(params)
              return {
                  q: params.term,
              };
          },
          processResults: function (data, params) {
              var results = [];
              console.log(data)
              $.each(data.items, function(index, user) {
                  if (user.cars.length > 0) {
                      $.each(user.cars, function(carIndex, car) {
                          results.push({
                              id: user.id,  
                              text: user.first_name + " " + user.last_name + (car.plate ? " / " + car.plate : ""),
                              user: user,
                              car: car ? car : null,
                              usercar: user.car_users ? user.car_users[carIndex] : null  
                          });
                      });
                  } else {
                      // Si el usuario no tiene coches, aún lo añadimos al resultado
                      results.push({
                          id: user.id,
                          text: user.first_name + " " + user.last_name,
                          user: user,
                          car: null,
                          usercar: null
                      });
                  }
              });

              return {
                  results: results
              };
          },
          cache: true
        },
    });

For the stepper I am using this simplified script:

document.addEventListener('DOMContentLoaded', function (e) {
    (function () {
      const stepsValidation = document.querySelector('#multiStepsValidation');
      if (stepsValidation) {
        // Multi Steps form
        const stepsValidationForm = stepsValidation.querySelector('#orderCar-form');
        const validationStepper = new Stepper(stepsValidation, {
          linear: false  // Cambiar a false ya que no usaremos la validación lineal
        });

        const stepsValidationNext = [].slice.call(stepsValidationForm.querySelectorAll('.btn-next'));
        const stepsValidationPrev = [].slice.call(stepsValidationForm.querySelectorAll('.btn-prev'));

        stepsValidationNext.forEach(item => {
          item.addEventListener('click', event => {
            validationStepper.next();
          });
        });

        stepsValidationPrev.forEach(item => {
          item.addEventListener('click', event => {
            validationStepper.previous();
          });
        });
      }

    })();
  });
