Describe the bug
A few days ago, I successfully installed Isaac Lab 2.2 and Isaac Sim 5.0.0 following the official tutorials. I was able to run the relevant example scripts and completed basic RL training with the JetBot. However, when I tried to use it today, I found that I could no longer run any projects successfully — they all throw the following error:

Additional context
I can launch Isaac Sim normally by running isaacsim — no issues there.
I tried the workaround in isaac-sim/IsaacLab#1937, but the exact same error still occurs.
