Hey @JdB thanks for trying out the 2.0 alpha, we appreciate it!
My immediate guess is a Newtonsoft dll conflic, quite common if other gh/phino plugins are using an older version. A quick test to see if that’s the case is to temporarily disable all other Gh&Rhino plugins:
- for Rhino you can disable them from the settings
- for Gh, you can temporarily move their .gha and related folders/s files to a different location
From our side, if that’s the issue, we can get Newtonsoft to load as an alias, and that should do the trick!
