Help Obi missing scripts and not working on import

[robert.nally]

Hi,

I just imported Obi Rope into my project.  I also updated / imported the backend packages like the mathematics package, jobs packaged, burst package, etc.

When I go to a scene in the package to try out what's there I get missing script errors.  The current scene (picture attached) doesn't respond.

I'm on Unity 2019.4.40 with the built-in render pipeline.

Any idea what could be causing this issue?

Thanks,
Rob
