No disk for Recovery after erasing Monterey
On a Macbook Pro (13" M1 2020), after installing Monterey, I erased the system disk in Recovery, but I am unable to reinstall Monterey because Recovery sees no disk. The base system is still present, a container for it, and the SSD fabric; the system will now only boot into Recovery. I also attempted to install Monterey onto different external drives. Recovery does see those drives but will not install Monterey to them.
I've been told by phone support that this is a hardware problem, but the system had worked fine for about two months until I installed Monterey. In Monterey I encountered a large performance problem with USB 2.0 IO: a copy between 2 external disks that had been taking about 2 hours was now taking 20. So I erased Monterey in an attempt to roll back to Big Sur. (I did not know that this has been disallowed for M1 machines, I presume because Monterey has much more software that runs natively on M1.)
