Error when trying to access config, can't use the module

I am not able to find the exact part of code which is causing this issue but when I replace the contruct interface and use this code it starts working properly.

public function __construct() {
$this->render = \Drupal::service('renderer')
}

There is some problem in either the DI or some conflict in ConfigFormBase class.

Please review.

Fixed the errors/warnings while applying the patch from the MR.

That works perfect with our codebase! Thank you so much!
