php bin/magento maintenance:enable composer require magento/product-community-edition=2.4.3 --no-update composer update php bin/magento cache:clean

rm -rf var/cache/*

rm -rf var/page_cache/*

rm -rf generated/code/*

php bin/magento setup:upgrade

all the steps where good until i reached this step : php bin/magento setup:di:compile

    Compilation was started.

Answer 1

As per your issue I would suggest you please disabled all third party extension while you upgrading Magento core libraries. once Magento core libraries updated you can update one by one your third party extension's then i hope everything will be working fine.

Still if you have any issue please let us know.
