Front nearside window won't open

[Divadiver]

Hi there, newbie here. I have a 2023 Leon VZ2, which I love. However, the front nearside window won't open. It's still under warranty and it's due to go into the garage on Monday - again, because it was there very recently having the entire infotainment system replaced, which I feel may not be unconnected to the problem. On the other hand, a search of Google suggests that it may be possible to 'child-lock' the front passenger window. I have searched the infotainment system, and Google, to find how this can be achieved and therefore undone, but am at a loss. Has anyone else had this problem? If this is a function of the car, I'd like to find out before I have to schlepp 40 miles to my nearest dealership! Any advice gratefully received.
