After the update, just turning on "self-healing" and a black screen. If you press "F1" when you turn it on, the inscription "Entering Setup" appears and that's it, it just hangs on it ....

Yes, both M.2 SSDs are fully functional. Tried the same in other M.2 slots. There is also no PXE boot option. MAC Address (Internal LAN): 00 00 00 00 00 00
