What should I do if an extension breaks after upgrading Magento?

If an extension breaks post-upgrade:

• Disable the module via bin/magento module:disable.
• Check for a version update compatible with Magento 2.4.8.
• Review logs for error traces.
• Get custom development to refactor code for compatibility.
