SQLITE_BUSY: database is locked

Saw this error in the log:

2019-11-21 23:25:39.010 ERROR : virtual-things: events.js:183

Also, noticed earlier that removing things was taking VERY long. I even made a gif, but of course when I made it it wasn't so bad.

Tried to disable it in the add-ons list. It was stuck on the highlighted state for a very long time. Then I checked in the logs:
