My Iphone 14 Pro Max screen is black put the Phone is on.

Last Night I finished using the Phone, I put it to charge on my night table. I wake up today, and my screen is black. I looked it up and I used the troubleshooting that everyone is using "Volume up, Volume down and Power on for 10 sec" while in charger, but nothing happen. I took the Phone out of the charge and try it again, but nothing happen. I try I few times but nothing happen. I'm stressing because I used my phone to login to my medical practice from home and now everything is black. I need something fix immediately, I can't wait until tomorrow because I have to work.

Can someone help?
