It seems like Yii::app->request->post() can also be of type object; however, parameter $data of yii\base\Model::load() does only seem to accept array, maybe add an additional type check?

If this is a false-positive, you can also ignore this issue in your code via the ignore-type annotation
The expression return $this->redirect(a...e . '/admin/settings')) returns the type yii\web\Response which is incompatible with the documented return type string.
This check looks for calls to methods that do not seem to exist on a given type.
It looks for the method on the type itself as well as in inherited classes or
implemented interfaces.
This is most likely a typographical error or the method has been renamed.
