Issue Description:
I encountered errors while debugging the standalone script hello_world.py located at standalone_examples/api/isaacsim.simulation_app/hello_world.py, following the instructions from the Isaac Sim Debugging Documentation.
My OS:
➜ ~ uname -a
Linux ztr 6.8.0-57-generic #59~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Mar 19 17:07:41 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
Additionally, I am unable to attach the VS Code debugger to a running instance of Isaac Sim 4.5 using the same documentation.
Relevant Documentation:
Debugging With Visual Studio Code — Isaac Sim Documentation
Request for Assistance:
Could someone help me troubleshoot these issues?
