HA unresponsive after initial install/bootup : System Autofix complete

Hi,
I am new to HA,
I followed the tutorial to install HA on RASPI 5/4GB RAM from SD card, but I can not get through the last log message : System Autofix complete. After showing that for few minutes, OS seems to shutdown (yellow LED truns to red, from previously IP visible in the LAN, no longer is present) replacing SD card did not help.
Any ideas?
…last few lines from end of LOG:
