window regulator

hi guys

I own a BMW M4 2015 model and I can hear a grinding noise whilst trying to lower my O/S passenger window. I believe this could be the regulator but unfortunately the hard top was down when I noticed this and now it won't close.Does anyone know if that's the norm or should the roof still operate?

kindest regards
