Hey, this is a known issue. We’ll need a bit more data to figure out what’s causing the crash in your case. Try these in order: 1. Launch Cursor from Terminal with `cursor --disable-extensions`. If it works, the issue is caused by one of your extensions. 2. If it still doesn’t work, run `cursor --profile-temp`. This rules out your settings and profile state. 3. I need logs from Developer Tools: A similar issue on the same version 2.6.14 is already being debugged on [Windows](https://forum.cursor.com/t/the-problem-extension-host-terminated-unexpectedly-3-times-within-the-last-5-minutes-remain/154119) and [macOS](https://forum.cursor.com/t/cursor-socket-extension-missing-out-directory-on-macos-arm64-extension-host-never-starts-v2-6-14/154086), so it might be the same root cause. Let me know what you see in the logs. ---

Terminal sandbox could not start. This may be caused by an AppArmor configuration on your Linux system (kernel 6.2+). See the documentation for how to resolve this. What kind of error is this? ---

@Kira18 Two separate things here: Extension Host loading forever with no errors: this matches what we’re seeing from other users on 2.6.14 today. The `cursor-socket` extension might be missing files. Can you run this in your terminal and share the output? ```bash ls -la /opt/Cursor/resources/app/extensions/cursor-socket/ ``` (If Cursor is installed somewhere else, check `which cursor` or find the install path first.) If the `out/` directory is missing or empty, that’s the root cause. It’s the same packaging issue other platforms are hitting right now. Terminal sandbox error: this is a separate known issue on Linux with kernel 6.2+ and it’s not related to the Extension Host hang. More details and discussion here: [Terminal sandbox could not start](https://forum.cursor.com/t/terminal-sandbox-could-not-start/153056). For now you can safely ignore it. It only affects the terminal sandbox, not the agent itself. ---

@Priska Your error confirms the same issue. The `cursor-socket` extension is missing its `out/main` module. This is the same root cause as this macOS thread: [cursor-socket extension missing out directory on macOS arm64, Extension Host never starts (v2.6.14)](https://forum.cursor.com/t/cursor-socket-extension-missing-out-directory-on-macos-arm64-extension-host-never-starts-v2-6-14/154086). Can you run this and share the output? ```bash ls -la "/Applications/Cursor.app/Contents/Resources/app/extensions/cursor-socket/" ``` That will confirm what’s actually in the folder. We’re tracking this across all platforms on 2.6.14. ---

Hey all. This specific issue with `cursor-socket` should be fixed in 2.6.18! Please [download the latest version](https://cursor.com/download) (if your client hasn’t auto-updated). ---

Hey all. I think it’s important that we sepearate two issues: 1. The issue specifically related to `cursor-socket`, which should now be fixed 2. “Waiting for Extension Host” issues, which can be a symptom of many different issues. Since this thread was specifically about `cursor-socket`, if you’re still facing a “Waiting for Extension Host” issue, please follow the steps @deanrie outlined above and raise a new thread. > [@deanrie](#): > > Try these in order: > > 1. Launch Cursor from Terminal with `cursor --disable-extensions`. If it works, the issue is caused by one of your extensions. > 2. If it still doesn’t work, run `cursor --profile-temp`.

I need logs from Developer Tools: > > - Open the Console tab > - Wait for the error “Waiting for Extension Host” or “Extension host terminated” > - Copy all red errors and paste them here If the issue is still related to `cursor-socket`, please follow up here! ---

Hi, I had the same problem today (it’s funny that I didn’t need AI until the end of the workday, and then I kept getting timeouts and “waiting to host” messages…) I left it alone for about 20 minutes, then tried again, and it started working again. The problem isn’t with the editor or the extensions (I haven’t installed any in the last few weeks)—the problem is on your end. I understand that software development is complex, but I’ve already created a lot of threads here about issues. I use Windsurf separately, and unfortunately (unfortunately for you), it works much better, and token usage is cheaper too. Try a little harder 😕 When I go to work, I wonder, “Won’t there be another update that breaks something for me?” [Next page](https://forum.cursor.com/t/cursor-2-6-waiting-for-extension-host/154134.md?page=2)
