Magento 2.4.2 not showing products in category pages after update, this is what I get into the var\log\exception.log:

main.CRITICAL: Class Magento\Catalog\Helper\HelperNew does not exist {"exception":"[object] (ReflectionException(code: -1): Class Magento\\Catalog\\Helper\\HelperNew does not exist at /home/customer/www/mywebsitename.net/public_html/vendor/magento/framework/Code/Reader/ClassReader.php:24)"} []

I have already tried to upgrade, compile, reindex, clear and everything from putty as I said here Magento 2.4.2 not showing products in category pages after version update , but nothing, what about the errors I just posted, any help with that?

Please try to check that your Elasticsearch is working or not
for Magento 2.4 versions Elasticsearch is compulsory.

I changed the Store View from All Store Views to the store in question, selected the category with the problem, and noticed that the category settings were not selected to use the default value.
Selecting the options to use default value works.
Just double-check on the store view.

I had the same problem you described, tried the same steps you outlined, tracked down the same collection query. Ultimately the cause was a product attribute added by a third-party extension, said attribute was improperly configured.

Do you have more details on that?

Hello,

You need to follow this steps.

1. Search following class into all third party extensions.

Class Magento\\Catalog\\Helper\\HelperNew

 
2. Now disable those extension.
3. Run all the commands like upgrade, deploy, caching etc.

Hey,

you can see in screenshot there is no such class available in magento as i think third party extension use that class, so you need to find which extension use that class using below command grep -rnw app/ -e 'HelperNew' -- for check in app directory grep -rnw vendor/ -e 'HelperNew' -- for check in vendor directory if you find any extension that use that class please disable that extension using below command php bin/magento module:disable Vendor_ModuleName and run the upgrade and deploy command
