Restarted HOST and HA not starting

Made a shutdown of host (R Pi + SSD) and HA is not starting (and nothing is showing in the logfile).

This morning I restarted the host and after it worked fine and in the meantime no changes were made.

Any idea how I can troubleshoot this problem? I am running HA in a docker

In my opinion it seems Supervisor is not starting, but I am not an expert of such things. Any help will be appreciated. (Note I should have backup taken during the night)

EDIT - it seems docker is not starting
