How I can find what is wrong there? I mention that in the M2.3.3 version everything was work fine.

Thank you in advance

EDIT:

I have there in the admin of categories a custom attribute, I add this attribute and I add the following code in: HS/GroupedProduct/view/adminhtml/ui_component/category_form.xml

        </field>
    </fieldset>
</form>

is something wrong with this?

enter image description here

Edit:
if I comment out this lines of code everything is working fine and the category save is working perfect. It is a Magento 2.3.4 BUG?

       if ($this->isCategoryAttributeChanged($designAttribute->getAttributeCode(), $category)) {
            $this->cacheTypeList->invalidate(
                [
                    \Magento\PageCache\Model\Cache\Type::TYPE_IDENTIFIER,
                    \Magento\Framework\App\Cache\Type\Layout::TYPE_IDENTIFIER
                ] 
            );
            break;
        }

This error may be custom attribute then you can find this way..
Go to Below file and uncomment below line
1) app/bootstrap.php, there is:

ini_set('display_errors', 1);

2) Run below commands

php bin/magento deploy:mode:set developer
php bin/magento cache:clean
php bin/magento cache:flush

and you can replace wysiwyg attribute with this
