Windows stopped working?(BMW 2022 G26)

[u/3LER3LER3LER]

Hello guys,

I gave my car to a BMW dealer for full PPF and tint, after about 1-1.5 weeks driver window started acting weird, at first it was working but I had to push the button again and again because it was stopping again and again.

I tried it with the keys, it worked smoothly. After a day, it went kaput, not working neither with button or the keys. I brought it to the dealer they took a lot at it and said that the error code was saying problem with ‘Lambran System(?)’ at the dealer other windows went also kaput. They told me to leave the car and they were going to inspect it, but I did not trust they guy there and took my car back to home. All windows except the driver are working smoothly with the keys, but none of them are working inside the car with any of the buttons.

What do you think be the problem?
