I have a problem with the page builder on my custom module. In the adminhtml, everything is working fine, and my code propeller is saved to DB, but when I'm trying "echo" my code, the widget isn't displayed. I can see for example {{widget type="Magento\Cms\Block\Widget\Page\Link" anchor_text="test" title="test" template="widget/link/link_block.phtml" page_id="1"}} instead of my widget. Does anyone know how to render this code?

Use this class

use Magento\Cms\Model\Template\FilterProvider;

I fixed this issue with:

public function generateHtmlWithWidgets($html): string
{
    return $this->getCmsFilterContent($html);
}

private function getCmsFilterContent($value = ''): string
{
    return $this->filterProvider->getPageFilter()->filter($value);
}

public function _prepareLayout(): Column
{
    return parent::_prepareLayout();
}

and on .phtml file:

  $pageBuilder = $block->getPageBuilder();
  echo $block->generateHtmlWithWidgets($pageBuilder);
