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: ![image](https://global.discourse-cdn.com/nvidia/original/4X/5/5/b/55bb61a7431a9f75ac9d52029b09b32b9f5a37ea.png) ---
