HA stopped working after snapshot reload


I’ve reinstalled my hass.io and tried to reload the configuration from a previously saved snapshot. After I did HA stopped working - SSH and samba work, only the GUI of HA is not working. I have no idea what the problem is. All I could find was this error in the supervisor log:

ERROR (SyncWorker_18) [hassio.addons.addon] Addon core_configurator have wrong options -> Missing required option ‘password’… Got {‘username’: ‘admin’, ‘password’: None, ‘certfile’: ‘fullchain.pem’, ‘keyfile’: ‘privkey.pem’, ‘ssl’: False, ‘allowed_networks’: [‘’], ‘banned_ips’: [‘’], ‘ignore_pattern’: [‘pycache’]}

Does anyone have any idea what I should do to fix this?
