I have came with this alternative solution if you have have existing thumbnails images and you want to add to alt text to existing images
then i have done that by doing this

function custom_module_entity_load(array &$entities, $entity_type) {
  if ($entity_type === 'media') {
    foreach ($entities as $media) {
      if ($media->hasField('field_media_image') && !$media->get('field_media_image')->isEmpty()) {
        $media_image_field = $media->get('field_media_image');
        $alt_text = $media_image_field->first()->get('alt')->getValue();
        $media_target_id = $media_image_field->first()->get('target_id')->getValue();
        if ($media->hasField('thumbnail') && !$media->get('thumbnail')->isEmpty()) {
          $thumbnail_field = $media->get('thumbnail');
          $thumbnail_item = $thumbnail_field->first(); 
          if ($media_target_id === $thumbnail_item->get('target_id')->getValue()) {
            $thumbnail_item->set('alt', $alt_text);
          }
        }
      }
    }
  }
}

So far what i have done is in my custom module using form alter hook
**
* Implements hook_form_alter().
*/
function custom_module_form_alter(&$form, FormStateInterface $form_state) {
if ($form_state->getFormObject() instanceof \Drupal\media\MediaForm) {
$form['actions']['submit']['#submit'][] = 'custom_module_process_alt_text';
}
}

/**
* Custom submit handler to set alt text for media images and thumbnails.
*/
function custom_module_process_alt_text(array &$form, FormStateInterface $form_state) {
$media = $form_state->getFormObject()->getEntity();
if ($media->hasField('field_media_image')) {
$current_alt_text = $media->get('field_media_image')->first()->get('alt')->getValue();
if (!empty($current_alt_text)) {
$reflection = new \ReflectionClass($media);
try {
$method = $reflection->getMethod('updateThumbnail');
$method->setAccessible(true);
$thumbnail_field = $media->get('thumbnail');
if ($thumbnail_field) {
$thumbnail_field->alt = $current_alt_text;
}
$method->invoke($media);
}
catch (\ReflectionException $e) {
\Drupal::logger('simple_media_bulk_upload')->error('Error updating thumbnail alt text: @message', [
'@message' => $e->getMessage(),
]);
}
$media->save();
}
}
}
this code is useful when in manage display you are using format as thumbnail i have done this way

The alt text is skipped in media image when uploading through bulk upload and in manage display format is selected as thumbnail but it works fine we change the format to render entity than it works fine

Update the patch to work with the latest release of textfield_counter thanks to the work done by #2 and #3

I updated the code to reference the validation method using the class name (static::class) instead of dynamically deriving it. This ensures the method is correctly called on the class using the trait, resolving the instantiation error.
The issue in #8 patch was this code originally attempted to call the validateFieldFormElement method using a dynamically derived class name from traits, which caused an error because traits cannot be instantiated or referenced in this manner. So i update the patch

@pgn5qs i m facing the same issue can you kindly tell me the steps that how you have over come that issue Kindly
