Hi, when I enable anim.people extension using python and load a person USD into the stage and then I use clone to duplicate the person. Sometimes it catch a crash.
Without enable anim.people via the python code the load USD and duplicate is fine.
Thank you for bringing this issue to our attention. To help us diagnose the problem with the Anim.People extension crash when cloning, could you please provide the related log files? These logs can offer valuable insights into what might be causing the crash.
Additionally, if possible, include any error messages or screenshots that appear when the crash happens.

I upload the sample code to reproduce this crash. The file also contain the output from my terminal.
For my test, I change the REPLICATE_PHYSICS and COPY_FROM_SOURCE parameters for clone function.
If I set
REPLICATE_PHYSICS = False
COPY_FROM_SOURCE = True
I do not get the crash, however, as the crash does not enter every run. This is a simple test.
If I set
REPLICATE_PHYSICS = True
COPY_FROM_SOURCE = False
as shown in the sample code. I meet a crash.
I use Isaac sim 4.1.0
Thank you for providing the detailed information. We have been able to reproduce the issue you reported. The crash occurs due to a problem with the omni.anim.skelJoint when copying the human asset.
We have created an internal ticket to address this issue and will provide updates as soon as we have more information or a resolution.
Please try adding simulation_app.update() between spawning the character and using the cloner.
