Think twice before doing an erase/reinstall on your M1

They're new instructions and they stipulate to select "erase volume group" which seems to be an important part of not causing problems.
You can't get past that screen. Go to post #26 in this thread and follow those instructions.
Found a Reddit thread with a possible solution. Seems to be a bug or at least wrong instructions on the Apple support page
Got it. Thanks. But I can't get the reset password popup to show. But I've removed the computer from my iCloud account and got the option to erase Mac. Currently installing
I see. I'm not sure that is proven. In my case, I deleted the Mac HD and then deleted Data afterward, together which I assume is the group. After that I got the same error message as Dockland.
No, that's not the same thing and is possibly why you're having this problem.
Either follow @SpeQ 's instructions or go to the previous Apple instructions here

from after "Use Apple Configurator"
Seeing as how @Dockland got the same results as me, it doesn't sound much different as far as results go.
My understanding is they erased the group, following the instructions you posted.
Good to hear.
Just for the future can you confirm that you chose "erase volume group" from bottom left whilst in Disk Utility please?
It matters, as if you did that it makes Apple's new instructions wrong.
Thanks.
My theory (and it’s only a theory) is there’s something additional happening when you erase via Recovery Assistant, as opposed to using Disk Utility, (which confusingly is also in Recovery Assistant). When you erase via Recovery Assistant, you get that Activate Mac screen, which I think must be a necessary component in the process. It may also be a part of the resetpassword process, but regardless, it seems to be necessary and it doesn’t happen using Disk Utility alone.
Disk Utility works fine, just a few extra clicks. I actually prefer using that because you don't have to boot into Recovery.
I followed these instructions using Apple Configurator and the actual part of entering DFU & restoring the drive took roughly 10 minutes. Maybe less. I’m restoring from a Time Machine backup now via a USB-C WD Drive and it’s showing it’ll be about another 3 hours to finish. That’s for roughly 1½ TB of data on my “Macintosh HD” Drive.
Revive or restore a Mac with Apple silicon using Apple Configurator 2
In rare circumstances, Apple computers become unresponsive and the chip’s firmware must be revived or restored.

I see it says that in the instructions. Have you actually tried those instructions?
