I am running a rhino.compute project on Kubernetes and I am encountering the error System.AccessViolationException at Rhino.Geometry.Curve.ToNurbsCurve(). I am using RhinoCommon version 7.0.20314.3001 in custom code and rhino inside version 7.0 in compute.geometry. is there a way to avoid this?

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

You probably should first update to the very latest release of Rhino 7 and RhinoCommon - for both that’d be 7.38, but even 7.37 should be fine - and see if the issue still happens with that.
