iPhone 13 Pro Max screen itself turn Pink (purple) and can’t open

My phone has only been unboxed formore than 10 days, no drops, no water.

I was using it, but the screen turned pink and there was no way to open it. I tried to turn off but it didn't work.

pink screen and shutdown, pink and off, ….. non-stop

It continued the next morning. I'm too tired. 😓😓😓😓😓😓😓😓

Why? And and what should i do to fix it?
