[sochongl]

Hi,

I have unistalled and reinstalled isaac sim 2023.1.0 several times and each time I want to run isaac-sim as GUI, I am facings issues which prevent me to access practically all the extension examples.

Contrary to running standalone examples through python.bat, that is actually doable.

Could you please give any hint what is happening?

Kind Regards,

[sochongl]

I attach the full log:
kit_20231101_091736.log (1.9 MB)

I can execute standalone examples so I just don’t know what is wrong when I try running as GUI.

I am looking forward for your reply.

@sochongl looking at the log, a few lines caught my attention:

do you have ros2 bridge extension enabled by chance? if so, i would encourage you to refer to this pinned thread by the dev -

Running the new Isaac Sim ROS/ROS2 Bridge (Isaac Sim 2023.1.0 Release onwards)

Dear Users, The workflow for running the ROS/ROS2 Bridge on Isaac Sim has changed in our latest release of Isaac Sim 2023.1.0! Isaac Sim is now able to use your system level or custom ROS/ROS2 installation! ROS/ROS2 Installed on the System If you have (or planning to have) a system level ROS/ROS2 installation, please follow the installation guide to ensure you have all of the required packages installed first. If you are using the ROS2 bridge, make sure the FASTRTPS_DEFAULT_PROFILES_FILE envi…

Hi, it turned out that there was an issue with XR Experience extension, which I was using, I just disabled it and then reloaded Isaac Sim from isaac-sim.bat (as administrator) and then everything was fine.

Besides, with the hotfix recently provided, such problem has not been showing up so far.

Indeed, I followed the steps to install ros humble on windows, but that was not affecting the startup process.

Thank you for your suggestion though.
