[Bug Report] Why enable_camera tasks are not working in headless mode? specially when using server

[SouvickC]

Describe the bug

--enable_camera feature is not working while in headless mode.

Video recording is also not working due to this.

Can't verify when trained on server.

Is there a version mismatch?

following up on this bug.

Is there any ways I can run training with camera as observation input in servers (no display attached)?
If you have any workarounds that also will work before the fix.

The below example script is also not working.
python scripts/reinforcement_learning/rl_games/train.py --task=Isaac-Cartpole-RGB-Camera-Direct-v0 --headless --enable_cameras
