I had a similar exception on buster with deluge-gtk 1.3.15-2:

I googled a two-years old link (https://stackoverflow.com/questions/44691151/
deluge-cant-open-torrents) where someone saying that the directories in
Preferences -> Downloads must not be empty even if unmarked (I think the
values for those directories are None by default after install).
I did so and have no that exception now.
