Horizontal Lines started appearing on my Mac suddenly.

I have M1 Macbook air from 2021. It was working really well till yesterday. Suddenly 1 small horizontal line appeared and then after every few hours it is getting worse. It looks like its FLEXGATE for M1 Mac. I went through couple of posts on reddit and apple community forums. A lot of people are facing similar issues. Does anyone know how to fix it?

Any suggestion would be helpful.

PS: I didn't expect such bad quality from apple and I am really disappointed that even when so many people have faced this issue the problem still persists and they don't have any service program or support for the same!

MacBook Air 13″, macOS 12.5
