When we click on Live Preview button on node edit page or layout builder page, we get the following error:
Symfony\Component\HttpKernel\Exception\HttpException: The specified #ajax callback is empty or not callable. in Drupal\Core\Form\FormAjaxResponseBuilder->buildResponse() (line 67 of core/lib/Drupal/Core/Form/FormAjaxResponseBuilder.php).
Currently the code is replacing the default preview button with custom code block which is adding ajax callback. Instead of doing that we can add ajax callback to the preview button without replacing it.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Reviewed the patch and confirmed that it resolves the bug. It also resolves a bug that occurs as a result of the submit handlers being removed.
Thanks @KunalRatnani and @steyep for working on this, patch #3 applied and merged in main branch.
