[Bug Report] RL Games not working in debug mode

[robin-vetsch]

Describe the bug

Training of “Isaac-Reach-UR10-v0” environment in debug mode from VS Code with rl_games leads to the error: “exception: no description”. It only works when starting the file over the terminal.

Adjustments in the init.py file according #541 to have not been successful.

Steps to reproduce

I used the file:

/home/robin/IsaacLab/source/standalone/workflows/rl_games/train.py

and I get an error in line:

runner.run({"train": True, "play": False, "sigma": train_sigma})

here the error:

Exception has occurred: AssertionError

  File "/home/robin/IsaacLab/source/standalone/workflows/rl_games/train.py", line 170, in main
