"No such table" error in Kindle Voyage running Koreader

[idiom6]

I'm running Koreader on a KV and it worked fine a few days ago, but now I'm getting an error when I both connect and disconnect to my PC's USB port.

When plugging in:

I don't know what this means, nor how to fix it. (I also don't know if this is a Calibre issue or a Koreader issue)

I'm dumb, ignore me, I forgot the basic rule of troubleshooting: restart/reboot. Error messages went away.
