New install and got this error

Installed your plugin this week on one website and it worked fine with no errors. It looks like you added a feature recently… Added to a new website and got this error when saving the settings:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘Remove_Wordpress_Overhead\Remove_Wordpress_Overhead_Settings’ does not have a method ‘settings_assets’ in /srv/bindings/0d0bc4b0dfe04d12ad57a5605c54809a/code/wp-includes/class-wp-hook.php on line 288
