Screen goes black, system heating up, took me 2-3 hard shutdowns to get it back to working

I'm using MacBook Pro (15-inch, 2019). The screen turned complete black all of a sudden. When I tried to restart it, the system was heating up a lot but the screen was still turned off. I had to do 2-3 hard shutdowns to get it back to working. Don't know what the issue is, I've attached the problem report below. Need your help to diagnose this issue.
