add a code in your edit.php file

app/code/{vendor}/{Module}/Block/Adminhtml/{your folder}/Edit.php

<?php
namespace Vendor\Module\Block\Adminhtml\Your Folder;

use Magento\Backend\Block\Widget\Form\Container;

class Edit extends Container
{
 ......
.....
.....
 protected function _prepareLayout()
    {
        $this->_formScripts[] = "
            function toggleEditor() {
                if (tinyMCE.getInstanceById('post_content') == null) {
                    tinyMCE.execCommand('mceAddControl', false, 'post_content');
                } else {
                    tinyMCE.execCommand('mceRemoveControl', false, 'post_content');
                }
            };
        ";

        return parent::_prepareLayout();
    }
}
