We recently updated to 2.4.4 and we've since noticed that the "row" page builder section is no longer working.
When dragging the "row" section in a JS error is triggered:
Unable to load preview component (Magento_PageBuilder/js/content-type/row/preview) for row. Please check preview component exists and content type configuration is correct.
I've looked through other questions on Stack Overflow and cannot find anyone hitting the same problem.
