Whenever I open the Catalog Product it gives the following error on loop and continue loading the loader

Attention Something went wrong.

Something went wrong with processing the default view and we have
restored the filter to its original state.

I tried clear the cache(php bin/magento cache:clean)also upgraded magento(php bin/magento setup:upgrade)even given the files and folder permission but still facing the same problem.

Old post but for future viewers - a temporary fix is to clear (empty, not delete) the ui_bookmark table of your magento 2 database, this will reset the grid back to it's default and stop the infinite load.

(you can find out your admin user ID in the admin_users table as well and only remove the ui_bookmark rows relevant to your account if this is a multi-admin site)

The actual problem can be harder to diagnose, but a good place to start (and in my case) was to increase the php timeout limit.

File open: vendormagentoframeworkViewElementUiComponentDataProviderFulltextFilter.php

Function change:

public function apply(Collection $collection, Filter $filter)

{

    if (!$collection instanceof AbstractDb) {

        throw new InvalidArgumentException('Database collection required.');

    }



    /** @var SearchResult $collection */

    $mainTable = $collection->getMainTable();

    $columns = $this->getFulltextIndexColumns($collection, $mainTable);

    if (!$columns) {

        return;

    }



    $columns = $this->addTableAliasToColumns($columns, $collection, $mainTable);

    $collection->getSelect()

        ->where(

            'MATCH(' . implode(',', $columns) . ') AGAINST(?)',

          //  $filter->getValue()

            $this->escapeAgainstValue($filter->getValue())

        );

}

This commit can solve your problem.

It was due to that some null SKU related error I resolved using the following query.

UPDATE catalog_product_entity SET sku='' WHERE sku IS NULL;
