Got my 16" M1 Max mid-January, water damage and repair in mid-February, then bricked on 12.3 (standard) update attempt on March 14. Took it to the closest Apple store, they did not have the parts, so they sent me to one a bit further away. Apparently the new parts were in stock and repair was attempted. Notice on the support page still shows it is being "Running final quality checks" as of March 18. It did not complete the repair. Began calling to get updates, and I understand all the turmoil, but there has been no progress and I am not sure that the technicians know that this is not a reparable issue. I was told it was unique until I pointed out that it was in the news and on Apple News. They are trying once more to fix it, and I have been assured that there is a replacement computer waiting if/when this repair fails. Hopefully I will get a computer back today or tomorrow. I think the issue is that the T2 chip has been so "hardened" that it even rejecting Apple authorized parts, and will not accept any changes to factory installed hardware, even when done by the manufacturer. It's a huge bug unless Apple is willing to give out new computers each time there is a repair, which is not sustainable. (Sorry, we've reduced the packaging and taken out the charger and the headphones to save the environment, but if your device fails, we need to chuck it and give you a new one, but there is no wasted plastic or paper here) I just hope that they can issue a firmware update. The "right to repair" also includes the possibility that your computer is not disposable.
