OpenCutList Stopped Responding While assigning materials to model compnents

Hello SketchUp Experts,
During assigning materials to my SketchUp Cupboard model, the OpenCutList stopped responding. I have tried to reinstall the OpenCutList in my SketchUp, but no luck in reactivating generating my Cutlist of my model. I am using SketchUp Pro with an average level of experience and using OpenCutList for the first time. Any hints to diagnose my problem and how to resolve the issue is highly appreciated.

Thanks,

Have you reached out to the OCL group? I believe there is a way in the extension to contact and interact with the Developer. There may also be a forum.

Thank you RLGL for your suggestion.
