OperationalError: database is locked

Hi,

Lately I have been getting these errors more often when I launch my app. It seems to happen more in the evening here, I don’t know if that plays any role in it. The error persists until I reload, though it usually goes away after that. What’s the cause of the database is locked errors?

I encountered the issue several times a moment ago again. Has anyone else encountered this problem recently?

Still ongoing. Could I get any information about this please?
