I did upgrade the Magento version from 2.4.2 to 2.4.3 when run command upgrade show an error Unable to apply data patch Magento\CatalogSampleData\Setup\Patch\Data\InstallCatalogSampleData for module Magento_CatalogSampleData. Original exception message: Rolled back transaction has not been completed correctly.
I did fix the issue with the command: php bin/magento sampledata:remove because I upgrade magento version from 2.4.2 to 2.4.3 and did not use sample data so it show error when upgrade and currently did fix
