PROBLEM: Strange behavior on IsaacLab-Arena Docker

[mat-macnica]

Hello,

Thank you very much for your prompt answer like below.
I really appreciate your help.
So, I can run "./docker/run_docker.sh -g"
#396 (comment)

But after adding below commands to Dockerfile.isaaclab_arena, we found another problem like below;
"RUN /isaac-sim/python.sh -m pip install --no-build-isolation flatdict==4.0.1"

So, I would appreciate if you check the behavior & tell us how to solve this problem.
Best regards,
