Hi @lizih375,
This is a GPU architecture incompatibility – Isaac Sim 4.5 does not support Blackwell (RTX 50-series / RTX PRO 6000) GPUs. The log line:
[gpu.foundation.plugin] Skipping NVIDIA GPU due CUDA being in bad state
confirms that Isaac Sim 4.5’s rendering pipeline cannot recognize your RTX PRO 6000’s SM 12.0 compute capability, since it was released before Blackwell GPUs existed. No driver change
will fix this.
All the other errors you see (ROS2 Bridge failure, OmniGraph node type mismatch, GUI crash) are downstream consequences of the GPU being skipped at startup.
Solution: Upgrade to Isaac Sim 5.1.0 or 6.0.0. Isaac Sim 5.1 supports the RTX PRO 6000 with driver 580.65.06 on Linux.
After upgrading Isaac Sim, you will also need to update the Isaac ROS workspace to a version compatible with Isaac Sim 5.1. The start_isaac_sim_franka.py script references old
omni.isaac.core_nodes node types that were renamed to isaacsim.core.nodes in 5.x.
