Hardware Failure of Display MacBook Air M2

Hi,

I have a Macbook Air M2 Chip. Almost 1.5 year old. The screen has stopped working suddenly with no physical damage but the laptop is working when connected to an external screen. (This I am writing on the external screen)

As per apple support and service centre , it's been told that there's a hardware failure with the machine with no valid reason behind it.

Now,

1. After waiting for several weeks,
2. Resetting the system,
3. and endless calls.

the actual reason for this hardware failure has not come out.

What I don't understand is, how a machine this expensive can suddenly stop working and why is no one able to provide me with a proper explanation for the same?

Attaching the screenshot of System Information>Hardware section with this where we can see there's no Display hardware reflecting.

So if anyone can help me with what should I do next in order to get this things fixed ! (PS: without paying hefty amount on no reason Display failure), that'd be great!
