I’ve solved the issue… how? I had an AIO migration backup, and it was restored correctly. The mistake was caused by poor design in your UI. I copied the key from the old site to the new one. I blame you because there are no warnings or a defined section, like “import” or “export.” Thanks for stating the obvious in your response. If a plugin doesn’t work, that’s fine, but if the plugin crashes your site and there’s no undo button, it must be the worst plugin ever.
