Error to create or edit existent

Problem/Motivation

As mentioned in the title, I have the following error when creating or editing:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /admin/content/block/88?ajax_form=1
StatusText: parsererror
ResponseText: TypeError: Drupal\Core\Render\MainContent\AjaxRenderer::renderResponse(): Argument #1 ($main_content) must be of type array, null given, called in /var/www/trexperienceperu.com/core/lib/Drupal/Core/Form/FormAjaxResponseBuilder.php on line 89 in Drupal\Core\Render\MainContent\AjaxRenderer->renderResponse() (line 49 of /var/www/trexperienceperu.com/core/lib/Drupal/Core/Render/MainContent/AjaxRenderer.php)."
