Does not work with Drupal Profile fields

Actually it does work but it looks like I have a few theme issues going on. Apols

OK I double check and it does not work. Here' s a fix for ManageComponentAttributesForm.php

<?php

namespace Drupal\layout_builder_component_attributes\Form;

use CssLint\Linter;
use Drupal\Component\Utility\Html;
use Drupal\Core\Ajax\AjaxFormHelperTrait;
use Drupal\Core\Config\ConfigFactory;
use Drupal\Core\Form\FormBase;
use Drupal\Core\Form\FormInterface;
use Drupal\Core\Form\FormStateInterface;
use Drupal\layout_builder\Controller\LayoutRebuildTrait;
use Drupal\layout_builder\LayoutBuilderHighlightTrait;
use Drupal\layout_builder\SectionStorageInterface;
use Drupal\layout_builder\LayoutTempstoreRepositoryInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;

class ManageComponentAttributesForm extends FormBase implements FormInterface {
  use AjaxFormHelperTrait;
  use LayoutBuilderHighlightTrait;
  use LayoutRebuildTrait;

  protected $sectionStorage;
  protected $delta;
  protected $uuid;
  protected $layoutTempstore;
  protected $configFactory;

  public function __construct(LayoutTempstoreRepositoryInterface $layout_tempstore_repository, ConfigFactory $config_factory) {
    $this->layoutTempstore = $layout_tempstore_repository;
    $this->configFactory = $config_factory;
  }

  public static function create(ContainerInterface $container) {
    return new static(
      $container->get('layout_builder.tempstore_repository'),
      $container->get('config.factory')
    );
  }

  public function getFormId() {
    return 'layout_builder_manage_attributes_form';
  }

  public function buildForm(array $form, FormStateInterface $form_state, SectionStorageInterface $section_storage = NULL, $delta = NULL, $uuid = NULL) {
    if (!$section_storage || $delta === NULL || !$uuid) {
      throw new \InvalidArgumentException('ManageComponentAttributesForm requires all parameters.');
    }

    $this->sectionStorage = $section_storage;
    $this->delta = $delta;
    $this->uuid = $uuid;

    $config = $this->configFactory->get('layout_builder_component_attributes.settings')->get();
    $section = $section_storage->getSection($delta);
    $component = $section->getComponent($uuid);
    $component_attributes = $component->get('component_attributes') ?? [];

    $form['#attributes']['data-layout-builder-target-highlight-id'] = $this->blockUpdateHighlightId($uuid);

    $attribute_categories = [
      'block_attributes' => $this->t('Block attributes'),
      'block_title_attributes' => $this->t('Block title attributes'),
      'block_content_attributes' => $this->t('Block content attributes'),
    ];

    foreach ($attribute_categories as $category => $title) {
      if ($this->hasAllowedAttributes($config["allowed_$category"])) {
        $form[$category] = $this->buildAttributeFieldset($title, $config["allowed_$category"], $component_attributes[$category] ?? []);
      }
    }

    $form['actions']['submit'] = [
      '#type' => 'submit',
      '#value' => $this->t('Update'),
      '#button_type' => 'primary',
      '#ajax' => $this->isAjax() ? ['callback' => '::ajaxSubmit'] : [],
    ];

    $form['#tree'] = TRUE;
    return $form;
  }

  // Rest of the existing methods remain the same...
}

Here's a fix for layout_builder_component_attributes.routing.yml

layout_builder_component_attributes.settings:
  path: '/admin/config/content/layout-builder-component-attributes'
  defaults:
    _form: '\Drupal\layout_builder_component_attributes\Form\GlobalSettingsForm'
    _title: 'Layout Builder Component Attributes Settings'
  requirements:
    _permission: 'administer layout builder component attributes'

layout_builder_component_attributes.manage_attributes:
  path: '/layout_builder/update/block-attributes/{section_storage_type}/{section_storage}/{delta}/{uuid}'
  defaults:
    _form: '\Drupal\layout_builder_component_attributes\Form\ManageComponentAttributesForm'
    _title: 'Manage attributes'
  requirements:
    _permission: 'manage layout builder component attributes'
    _layout_builder_access: 'view'
  options:
    _admin_route: TRUE
    parameters:
      section_storage:
        layout_builder_tempstore: TRUE

Should now work with any fieldable entity.
