Deluge crashes when removing a torrent

[ExorDG]

Summary: Deluge crashed when trying to remove a torrent. Description: I use Deluge with Radarr. Deluge removed torrents just fine for roughly an hour and then crashed when trying to remove a torrent. Note that this happens all the time. Every time I open Deluge and then roughly an hour later, it crashes.

Here is the error message that is showing all over in its log.

04:02:10 [ERROR   ][deluge.ui.web.json_api            :185 ] [Failure instance: Traceback: <class 'deluge.error.InvalidTorrentError'>: torrent_id 05c4dc412ee69c5a21bf7d2bac306cd09e02f94c not in session.
