--enable_cameras is not working in headless mode in servers

[SouvickC]

This issue arises when it is using servers with cameras in them.
Tried with B200, T4, L4 GPUs. The issue is the same everywhere.
It is getting stuck at this stage; even it is getting stuck with standard IsaacLab examples

python scripts/reinforcement_learning/rl_games/train.py --task=Isaac-Cartpole-RGB-Camera-Direct-v0 --headless --enable_cameras

Raised a bug report already – #5171.
