@zarexogre, I have fix the issue. please kindly review the patch file

#3 - This patch creates a conflict because the module already imports the RenderArray class

use Drupal\rat\v1\RenderArray;

Which I don't seem to find anywhere though.

Marking as duplicate of 🐛 RenderArray not found in inline entity form render Needs review since that one has progressed further.
