Plugin loading fails in classic mode

What version of twisted? Update to the latest version. Also I think you need deluge 2.0.4dev if you have python >= 3.8.

Thanks for the answer.
I updated Twisted as below but the problem is the same.

The ability to install deluge development version is not available,
So I will give up.
Thank you.

I'm also having the same issue, however I downgraded to python 3.7 and still had the same issue.

[garretyoder]

I've also manually installed deluge 2.0.4 as mentioned and still receive the same error.

Edit: installing from git with the latest patch fixes this issue. The issue is not present in deluge==2.0.4.dev38.

[springjools]

If you downgrade to python 3.7 it should also fix the issue, but you have to make sure deluge uses that python. Anyway, it's not an issue related to this plugin but to deluge itself. More info here:
