Hey, thanks for the report. This looks like an extension host init crash. When it doesn’t start, settings, extensions, the agent, and the model selector can all disappear at once. It’s a known type of issue and it often shows up after an update.

A couple steps that usually help:

  1. Fully quit Cursor and do a clean reinstall of the latest build from Cursor · Download. Make sure it’s a reinstall, not an in-app update. Your settings and chats should stay.
  2. If that doesn’t help, open Help > Toggle Developer Tools > Console and share what you see in the logs when the window starts, especially lines about the extension host or timeouts.

Also, can you confirm if you see an error like Agent Execution Timed Out anywhere? That’ll help confirm the cause.

Let me know how it goes.

Hi, had the same issue + the terminal does nos start even if I kill the terminal and open a new one. Is it related ?

Hey, this is most likely the same issue. When the host processes don’t initialize after an update, extensions, settings, the model selector, and the terminal ptyHost can all break at once.

Try the same steps as above:

  1. Fully quit Cursor and do a clean reinstall of the latest build from Cursor · Download. It has to be a reinstall, not an in-app update. Your settings and chats should stay.
  2. If that doesn’t help, open Help > Toggle Developer Tools > Console and send what you see in the logs when the window starts, especially lines about extension host, ptyHost, or timeouts.

Also tell me your Cursor version and OS. And if you see an error like Agent Execution Timed Out anywhere, let me know too. That’ll help confirm the cause.

It’s been a clean install over old version (I don’t auto update, too many bugs).

Will try 3.7.21 today.

Thanks for the update. Let me know how it goes on 3.7.21. If settings, extensions, and the model selector come back, then it was an extension host initialization issue.

If the issue is still there on 3.7.21, please send the logs. Open Help > Toggle Developer Tools > Console right after the window launches and paste anything that shows up about extension host, ptyHost, or a timeout. That’ll help confirm the cause.

Waiting for your result.

3.7.21 and 36 work fine after installing over manually.

Glad it worked. The fact that a manual reinstall fixed it confirms it was an extension host init crash. When the host doesn’t start, settings, extensions, and the model selector all break at once. We’ve got this issue on our radar. It most often shows up after an in-app update, so reinstalling the latest build over the top like you did is a good workaround.

@123-VicMtn if your terminal or extensions still won’t start, try the same thing: fully quit Cursor and install the latest build from Cursor · Download over the top. Do a reinstall, not an in-app update. Your settings and chats will stay. If that doesn’t help, open Help > Toggle Developer Tools > Console right after the window launches and share what it shows about extension host, ptyHost, or any timeout.

The latest update probably fixed the problem, as it hasn’t happened since

Thanks
