iPhone 13 Pro Max suddenly bricked

I have been using iPhone 13 Pro Max since 1 year & it just went out of warranty on 19-10-2022.

Last night the phone was on 77% battery level when I left it on and unplugged on the table & went to bed. This morning when I woke up, I found that the handset is dead. It wont turn on & it wont charge. I tried to do the forced restart but nothing happened. Connected the handset to my Mac OS 13.0 but still the phone doesn't respond.

How does an iPhone which was working absolutely fine (having no physical damage) turn to be a BRICK at night without any warning or signs ?

How can I get the hand set to work again ?

Pls help.
