What is the reason: a sharp noise, the screen goes blank, the touchbar is active?

Question

macbook

Hello.

Macbook 16. I opened a video on YouTube, artifacts appeared on the screen, the sound froze (began to stutter in one place) and the system hung (nothing reacted). Turned off. Turned it on - after a while the coolers accelerated sharply and the screen turned off. At the same time, the touchbar remains active (when it is completely turned off, it cannot be pressed).

Pressing the power button triggers the shutdown sound (the touch is still active). If you press again after a while - again the sound and start of the laptop.

After starting after a while, coolers again and goes out again with the touch turned on.

What could be?

Now it freezes anywhere, artifacts appear and that's it :(
