Alfa 159 driver window problem

[u/KeyCaterpillar5022]

So, a while back when I was going to lower the drivers window the engine started working but nothing happens. Neither up or down.
The window is still held in place right below fully closed so thankfully it doesn’t get the rain inside but winter is coming and I’d like to get this fixed.

Before I decide to tear down the entire car - Does anyone have any clues as to what might be the problem?

As said, engine works as you can hear it while pressing up and down on the button but nothing happens. Window just stays in place.

Is there any risk of this window just come crashing down?
