Call to undefined method Drupal\views\Form\ViewsForm::getEntity()

This also happens when I try to create a new Block Type via Layout Builder.

I imagine the code introduced by 3436816 should not be executed on AddBlockForm. Not sure.

nilesh.addweb → made their first commit to this issue’s fork.

I've also got the same error and after resolving that i got another error
Error: Call to undefined method Drupal\views\Form\ViewsForm::getEntity() in field_formatter_class_field_widget_complete_form_alter() (line 142 of /var/www/html/web/modules/contrib/field_formatter_class/field_formatter_class.module).
so I have solve both in the MR !10.
Please review.

Thanks for the patch, in my case it fixed a WSOD on views bulk operations. It' now working again.
