Data at the root is invalid error

Hello, I’m having some troubles (hopefully not self-made(?)), using Hops.

I used to be able to use Hops, and worked with it regularely lately. I was trying to add some functionality to it, by allowing to export custom ironpython objects (which I didn’t succeed anyhow - maybe I’ll ask about that in another post).

I’m not sure, if I introduced the issue, which I’m encountering now by myself. I already tried to reinstall Rhino, Hops, dotnet, but the issue remains.

I would appreciate any idea on what I could try to resolve the issue.
