Hello @ahaidu, I have succesfully found the error. The bin/vulkan info command showed the warning that :
WARNING: [Loader Message] Code 0 : Layer VK_LAYER_MESA_device_select uses API version 1.2 which is older than the application specified API version of 1.3. May cause issues.
This means I somehow need higher API version for Vulkan layer loading. I found on their webpage that the maximum possible API currently is “1.2”. ( Vulkan-Loader/LoaderLayerInterface.md at v1.3.212 · KhronosGroup/Vulkan-Loader · GitHub)
And then I realised that it maybe occuring as I am using Isaac Sim 2022.2.1. Thus I ran the terminal for the version 2022.2.0 and everything has worked out just fine. I think Isaac Sim 2022.2.1 needs Vulkan Layer Loader to be of version 1.3.
I get a bunch of warnings but I think I can ignore these:
