Before you parked your car, were the windows open? If yes, did you close them from the toggles or from the remote? And after closing them and walking away from the car, did you look back at them?
I am asking because the window protection function might have been activated erroneously by the ECU. This function rolls down the window(s) if an obstacle is encountered between the window and the door frame. It may activate even if there's no obstacle, but the window rolls up slower or gets stuck.
This could be a starting point to look for the problem.
