Automatic Cracks on display of Macbook Air M1

Is there anyone having issues with the Display of Macbook Air M1 without your macbook being physically harmed ....

In my case I had put my macbook open for downloading some files and suddenly I see my macbook's display getting flickered and within few seconds I also see some internal cracks on the display which are not visible on the screen but inside the display..

Though its just been 5 months of purchasing the MacBook and I'm not getting the coverage for the display. I was blamed by the technicians of the service center that I must have done something wrong with it. I'm totally terrified with the after sale services and guidelines for the coverage.
