Windows > Extensions doesn't work

Omniverse Isaac Sim
1

I’m using Isaac sim 4.5 version. Suddenly, the Windows > Extensions doesn’t function. When I try to open Extensions tab, the Isaac sim crashes (Isaac Sim is not responding).

  • Other tools like, VS code extension, Robotics examples, under the windows function properly. The issue is only with extensions.
  • While opening the Isaac Sim application, the Isaac sim opens without any issue, but there are few warning messages which I haven’t seen earlier. The warning message is as follows:

  • Someone posted this issue earlier and suggested to try opening isaac sim after deleting .toml files inside the config folder. Didn’t work for me.
  • Also tried reinstalling the Isaac Sim multiple times, but it didn’t work.

Thank you for sharing the details of your issue. Just to clarify, are you saying there is another forum topic about a crash issue when opening the “Extensions” window? Could you please share the link here for reference?

Additionally, to help us investigate further, could you provide the full log file from your Isaac Sim installation?

That was a discussion and solution suggested in Stack Overflow. Not in Isaac Sim forum.

Here is the whole log file for your reference.

Hello @arunesh.srinivasan ,

Did you solve the issue?
Thanks in advance

No. Not yet.

@arunesh.srinivasan @vemulapk have you ever enable the isaacsim.code_editor.vscode extension?
@vemulapk could you also provide your full log?

I read a solution given by you in another post
set the vs code extension to false
Now, it works as normal. Thanks a lot.

Thank you. I’ll wait for @arunesh.srinivasan’s response to close this topic.

The suggested solution works.

But I need the VS Code extension to autoload, as I have to script using VS code.

Any suggestions??

Please try the workaround mentioned in the vemulapk’s post.
