Hi there,  
I follow the tutorial below but get the crash error as attached  
[https://docs.omniverse.nvidia.com/extensions/latest/ext\_replicator/shrubs\_and\_worker\_example.html](https://docs.omniverse.nvidia.com/extensions/latest/ext_replicator/shrubs_and_worker_example.html)

Is any idea to solve it?

@darien.wei i am a fellow user, and i would first suggest using the latest version of Code (2023.1.1) if you are still having this problem.
