Upgrade and Compile commands not working after update to 2.4.8?

After successfully upgrading to Magento 2.4.8-p1, php bin/magento setup:upgrade and php bin/magento setup:di:compile stopped working.

php bin/magento cache:cleanworks on the other hand. The error I get isCommand “setup:upgrade” is not defined.orThere are no commands defined in the “setup:di” namespace.`.

Tried to remove the vendor folder and running composer install, I am using PHP 8.3. I also tried setting the file and folder privs using find . -type f -exec chmod 664 {} ; and find . -type d -exec chmod 775 {} ;.

I also deactivated all 3rd party modules in config.php … nothing works. Running php bin/magento list shows no error.

I also deleted the generated folder and so on, nothing helps. The log shows:

[2025-07-10T11:13:33.240718+00:00] main.ERROR: Command "setup:upgrade" is not defined.

Did you mean one of these?
    magesetup:setup:run
    setup:db-declaration:generate-patch
    setup:db-declaration:generate-whitelist
#0 htdocs/vendor/symfony/console/Application.php(266): SymfonyComponentConsoleApplication->find('setup:upgrade')
#1 htdocs/vendor/magento/framework/Console/Cli.php(122): SymfonyComponentConsoleApplication->doRun(Object(SymfonyComponentConsoleInputArgvInput), Object(SymfonyComponentConsoleOutputConsoleOutput))
#2 htdocs/vendor/symfony/console/Application.php(175): MagentoFrameworkConsoleCli->doRun(Object(SymfonyComponentConsoleInputArgvInput), Object(SymfonyComponentConsoleOutputConsoleOutput))
#3 htdocs/bin/magento(23): SymfonyComponentConsoleApplication->run()
#4 {main} [] []

Basically, what it also outputs on the CLI.

Any ideas?

Thanks
