IsaacSim Crashing with the ZED Camera Extension

Software
1

Hello-

We’re doing some work evaluating the ZED cameras in simulation but running into an issue with the IsaacSim 4.5 crashing with the ZED extension installed on Windows 11.

We followed the tutorial in the documentation to the tee but the issue occurs every time we start a simulation.

Doesn’t appear to be a GPU issue since we are running a really simple simulation, IsaacSim indicates we have more than enough bandwidth, and we have meet the IsaacSim GPU requirements.

Let me know if there’s any thoughts on possible solutions.

Note: Here are some warnings I see in the IsaacSim console after starting a simulation.

Hi, could you run a diagnostic using the ZED Diagnostic tool installed with the ZED SDK and share the report?

Hi,

I confirm the crash. This should be fixed very soon. I’ll keep you updated.

Sorry for that.

Hi,

A new version of the extension (v3.1.1) containing the fix has just been published. It should be available in Isaac Sim in the next 24 hours once the extension registry is updated.
