I just updated to the latest version (8.7) and once it went to reboot it no longer came back up. After faffing about for ages and realising it wasn’t a dead USB stick, it seems it no longer boots if I have my USB hub connected which has my conbee 2 stick connected. I’ve had this setup for a long time at this point with no issues until tonights update.
If i let the system boot for 30-60 seconds and then connect the USB hub, all works absolutely fine. But of course this leaves me unable to remotely reboot and have the system come back up
