"Class Magento\Catalog\ModelCategory\Attribute\Backend\LayoutUpdate doesnot exist" in Magento2

Question

I am facing this issue when I trying to setup Magento2.3.2 p2 in my local system.

Admin is working fine. But in frontend I am getting the below issue.

Exception:Class Magento\Catalog\ModelCategory\Attribute\Backend\LayoutUpdate doesnot exist

I searched the web, but didn't find the solution.

Answer 1

if you were using Magento 2.3.4 and then downgraded to lower version, run the following:

DELETE FROM `eav_attribute` WHERE `attribute_code` = 'custom_layout_update_file';

Clear the cache.
