What steps should be taken to troubleshoot if the ds extension is not loading despite being installed?

If the ds extension is not loading despite being installed, you should first check if the extension is correctly enabled in your php.ini file. Make sure the extension_dir path is pointing to the correct directory where the ds extension is located. Additionally, restart your web server after making any changes to the php.ini file.
