I know it's of very little help, but I have not seen this issue, and I've been using Deluge for years (not automated via the arr suite, however)
It would do you well to find out what error it is throwing (check logs). Would be much easier to diagnose if you knew the actual issue.
I'm not super well versed in the world of app development, but I would assume due to the way apps are sandboxed, this isn't something that could be done with a third party app.
