Can't open USD with python script components

Environment Details:

  • Operating System: Ubuntu 20.04
  • CPU: i7-11700
  • GPU: RTX A6000, Driver: 525.125.06
  • RAM: 130GB

Project Setup:

I’m a beginner with Isaac Sim, currently working on building simulations for company projects. My USD project is opened from the extension [Isaac Examples → MyProject].

Issue Description:

I’ve encountered an issue where Isaac Sim completely freezes upon attempting to open a USD file that contains prims with Python script components. This freeze occurs irrespective of whether a default BehaviorScript or an EmptyScript is attached to the prims. These scripts are created by right-clicking in the Content Browser.

Additional Observations:

  • The USD files are otherwise functional; I can open versions that do not contain Python script components and manually add scripts to the required prims.
  • No warnings are displayed indicating that “the stage contains a script node” or that “USD includes Python Scripting Components.”
  • The system hangs indefinitely, as shown in the attached picture, without displaying any signs or messages.

Hi @jimlin - Can you please share your USD file to us, so that we can repro this issue?

Hi @jimlin - Also, this post might be helpful: Isaac Sim Crashes when I try to open a saved USD

Hi @rthaker, unfortunately, I can’t provide the detailed USD file, but I have created a simplified version so you can reproduce the issue. In the meantime, I’ve discovered that deleting all the action graph in my action graph resolves the problem. Additionally, opening the USD file in USD Composer doesn’t present any issues. The python scripting component is simply a default EmptyScript. Thank you!
