Error No Entity Framework Provider found for Devart.Data.SQLite

Error No Entity Framework Provider found for Devart.Data.SQLite

Hi! I maintain a .NET Framework 4.8 app that uses DevArt DotConnect for SQLite. It uses Entity Framework to talk to a database where application logs are stored. Anyway, starting about a year ago something changed in the app's config that's causing an error I don't know how to resolve. Here's the error message and call stack:

No Entity Framework provider found for the ADO.NET provider with invariant name 'Devart.Data.SQLite'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

Has anyone encountered an error like this one? I've tried all kinds of things to resolve it but so far no luck. Using DevArt's documentation to add settings to my app.config hasn't helped. I'm not sure what to try next.
