i did turn true to false about
exts.“isaacsim.code_editor.vscode”.carb_logs = false
in ‘exts\isaacsim.code_editor.vscode\config\extension.toml’

who do i fix it
plz help me

Is this issue related to auto-loading the isaacsim.code_editor.vscode extension? Could you please try launching with the --reset-user option to see if that resolves the issue? If it does, please help clarify the steps to reproduce the problem after performing the reset.

OK thanks for your reply, then how to reset with --reset-user option?
I’m usually launch isaac sim by ‘isaac sim,bat’.

@gustjr31321 There are two ways to do so per the official doc:

  • via app selector - you can launch isaac-sim.selector.bat (in the same location as isaac-sim.bat) and input --reset-user into Extra Args field. i believe you only need to do this once to reset the config and shader cache; you can return launching Isaac Sim as you would normally afterwards.

  • via command line - run the .bat with the --reset-user appended at the end as shown below:

Thank you reset option is work well.

Thank you very much. It works well.
