Duplicate entry in DB after upgrading to 2.4.3

I am having this strange issue when trying to upgrade magento 2.4.2p1 to 2.4.3

In bin/magento setup:upgrade

I get:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '543741' for key 'catalog_url_rewrite_product_category.PRIMARY', query was: ALTER TABLE `catalog_url_rewrite_product_category` ADD CONSTRAINT  PRIMARY KEY (`url_rewrite_id`)

I found entry in table

catalog_url_rewrite_product_category

entry

543741

and deleted it. But I still can’t setup:upgrade

I also tried to empty url.rewrite table but again no luck

I am stuck. Any help much appreciated!
