There has never been a laptop (or iMac) sold that didn't have crash issues, as far as I know. This particular issue appears not to be too serious, at least if it can be avoided for now by not scrolling comments while watching HDR. I've watched HDR without any issue, but I don't scroll comments while watching anyway.
with more awareness of this issue, I'm confident that it can be fixed, hopefully with a software update since there seems to be no hardware issues during diagnostics. We'll just have to wait and see what apple comes back to us with. They're getting back to me early next week from my u/l'd monitoring data and we'll go from there. I've also included these kernel panic threads from macrumors in my case file as ref as well.

My MBP M1Max 64gb 8Tb froze in the browser (both Safari and Chrome) after 14 days from new. The screen then went black, followed by the fan switching on full power followed by the MBP rebooting itself.

Apple Store ran diagnostics over 2 days. Nada. So with my OK they factory reset and clean install of OS.

Two weeks later issue arose again.

One cannot use a laptop if this occurs as you lose all the work you have been doing or risk it happening in the middle of an online financial transaction.

Apple refunded me.

They said monitor Forums to see when issue is resolved and then buy again once OS has settled down.

I have a number of the crash reports that I can post if anyone is interested..

I should add that one of the crash reports referred to the trackpad as a potential reason for the crash. There could be something in that. The trackpad maybe fully functioning mechanically but there could ba an issue with the software interaction between the trackpad and the screen... I'm not a technician but who knows. I also have a video recording of the frozen browser, the screen going black, the fan revving up and then the reboot.

I have faced the almost the same error with you. Do you have found any solution? Do you have any external monitors when it sleep?

Funnily enough I managed to get my MBP 16 to hard crash along these lines within 5 minutes of getting it!

I was playing around with some HDR videos on Youtube (in Safari) and it locked up. Not happened since.

Did you update the macOS? It was crashing first two months for many people with the bug.
