HA doesn't boot the second time after setting up

Hi HA Friends!

I’ve been running my HA for a few months and one day it just died. I was pretty mad and haven’t had enough patience to bring it to life again, but now the time has come.

Hardware setup: Raspberry Pi 3B+ booting from USB stick

The problem I have today:

  • Raspberry is booting HA from a USB drive freshly burned by Raspberry Imager
  • First launch works good, I can set up my account and so on
  • After the Raspberry power cycle nothing is working - HA is not booting, Rasp is not responding to pings, even led on my external USB drive is not blinking as when data is read but is just shining steadily.

Where the problem could be? Any ideas why it is not booting again?
