I’ve just encountered the same issue, no power outage that I am aware off but got the same error you did when loading the same screens.
I’ve powerred off the RPI for 5 minutes and then turned it back on and now I can’t connect to it at all, even connecting via ssh refuses to connect.
I didn’t back up hassio before powering off as I thought the error may be backed up, now I wish I had as I can imagine I may have to start from scratch again
