Isaac Sim Version
☑️ 5.0.0
(Other options unchecked)
Operating System
☑️ Ubuntu 22.04
GPU Information
Model: NVIDIA GeForce RTX 5090D
Driver Version: 580.82.09
Topic Description
Isaac Sim crashes with a segmentation fault immediately after adding a Ground Plane via the UI menu.
Detailed Description
I was attempting to set up a basic simulation scene by adding a physics-enabled ground plane using the built-in UI workflow. I expected a flat static collider to appear in the stage, as it does in previous versions or on other hardware. Instead, the application crashes instantly with a segmentation fault the moment I select Create → Physics → Ground Plane. The crash appears to originate in low-level CUDA memory management during USD/Hydra scene delegate initialization.
Steps to Reproduce
-
Launch Isaac Sim 5.0.0 on Ubuntu 22.04 with RTX 5090 and driver 580.82.09.
-
Wait for the empty stage to load successfully.
-
Click the top menu: Create → Physics → Ground Plane.
-
Application immediately crashes with
Segmentation fault (core dumped).

Additional Information
What I’ve Tried
-
Verified only one physical GPU is active (via
nvidia-smi). -
Confirmed system has ample RAM (64 GB) and VRAM (>22 GB free).
-
Launch command:./isaac-sim.sh --enable omni.isaac.ros2_bridge
-
The crash occurs even when no ROS 2 nodes are running—suggesting the issue is in core rendering/physics initialization, not the bridge.
