Cannot load the image_style entity with NULL ID. in assert()

In Drupal 9, after uploading the image and clicking the save button, the dialogue doesn't close, and the console shows the error:

{
    "message": "\nHubo un error HTTP AJAX.\nCódigo de Resultado HTTP: 200\nA continuación se detalla la información de depuración.\nRuta: /editor/dialog/image/full_html?_wrapper_format=drupal_modal&ajax_form=1\nStatusText: OK\nResponseText: AssertionError: Cannot load the "image_style" entity with NULL ID. in assert() (line 244 of /usr/home/comunidadperfecta/www/fasefundacion/core/lib/Drupal/Core/Entity/EntityStorageBase.php).",
    "name": "AjaxError"
}

I've just selected one of the responsive styles that are working in different parts of the web.
