Suddenly not booting

Had to reboot my Hassbian Pi. Worked flawlesly, diid not change anything. All of a sudden, it doen’t boot to home asssistant. It can be reached through Putty, I can see my log file. But no frontend, nog scripts working, nothing.

here my complete log ;

Found work-around, no sollution.
I’ve had this for awhile now too, someone mentioned it to me before but if you delete the config/.storage/core.config_entries file and then reboot, HA comes back up. You’ll have to rediscover the chromecasts again and it will lock up every reboot but if you have Samba/SSH working it’s easier than flashing a new Hassio image.
