iPhone 15 Pro Max Black Screen

I have had my iPhone 15 pro max less than a month and this is the second time I have experienced the black screen of death. It Normally happens possibly whilst charging my phone through the night. Come the morning I’m faced with the issue. The buttons make sounds and vibrations as if the phone is on. However I am unable to reset or turn the phone off and on. The first time lasted a few hours into the morning where I would receive calls and notifications, but unable to see or answer. The second time until my set alarm went off and then the phone reset itself
