Depending on the data that was added, you may be encountering a technical limitation that we've placed on file storage in the database. While we don't impose any strict limits on the length of data that you can save to a database field, something that is extremely long (for instance: text-encoded images, base64 images, file URLs, or lists of things) can result in slowed performance.

The solution here is to delete the database entry(s) impacting the performance. To do this, you'll want to create a new workflow to delete the entry with the proper unique ID referenced and attach this workflow to a button element that can be clicked in run mode.
