I have implemented a logging in vendor/magento/module-catalog/Model/CategoryLinkRepository.php

If there are multiple websites, Try to assign the product to that website first and then try again to update the product category.

vendor/magento/module-catalog/Model/ResourceModel/Category.php::getProductsPosition, I guess it's sending wrong $websiteId
