### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

I’m getting the “Extension host terminated unexpectedly 3 times within the last 5 minutes.” again (first time for me but I see several posts from '24 and '25).

I was re-installing my laptop and installed VS Code then Cursor. I used VS Code to install some of the usual extensions I use and then Cursor started giving the error.

Coincidentally, my MacMini updated to the latest version and started showing the same error even though I haven’t used it for several weeks except for updating cursor when I checked on it on that machine.

- all extensions are disabled
- I tried the “install cursor CLI” recommendation I have seen in other threads.

### Steps to Reproduce

Open Cursor

### Expected Behavior

Expect to use installed extensions but cannot.

### Operating System

MacOS

### Version Information

Version: 2.5.26 (Universal)  
VSCode Version: 1.105.1

Hey, thanks for the report. A couple things worth trying, since just disabling extensions in the UI might not be enough:

1. Launch from the terminal with extensions fully disabled:

2. Try a temporary clean profile:

3. Delete the state database (you’ll need to sign in again after this):

4. If nothing helps, try a full clean reinstall. Delete Cursor, then remove these folders, then reinstall from [https://cursor.com/download:](https://cursor.com/download:)

A few questions to narrow it down:

- Can you open Developer Tools (Help \> Toggle Developer Tools) before the crash, then send any red errors from the Console tab?
- How large are the projects you’re opening, roughly how many files?
- Which extensions were you using? Since you installed them via VS Code first, it might be a shared extension causing the crash.

The team is aware of stability issues with the extensions process in recent versions. Your report from two different machines helps us prioritize.

Let me know what you find.
