Hey, thanks for the report. Let’s quickly narrow down the cause.

Please check:

1. Extensions

- Run from terminal: `cursor --disable-extensions`
- If the crash stops, enable extensions one by one to find the culprit
- Also open `CMD+Shift+P` \> Developer: Open Process Explorer and send a screenshot right before the crash

1. Network and proxy

- Settings \> Network \> Run Diagnostics
- If you’re on a corporate network or using Zscaler/VPN, open App Settings with `CMD+,` search for HTTP/2 and enable Disable HTTP/2
- This helped with similar code 5 errors with Zscaler: [The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’)](https://forum.cursor.com/t/the-window-terminated-unexpectedly-reason-crashed-code-5/141617)  
Docs: [Common Issues | Cursor Docs](https://cursor.com/docs/troubleshooting/common-issues)

1. Clean environment

- Open an empty folder without a devcontainer and MCP, then check if it reproduces

Data needed for engineering:

- Help \> Open Logs Folder \> attach `main.log`
- Any errors from Help \> Toggle Developer Tools \> Console
- Confirm the results of `cursor --disable-extensions` and the test without a devcontainer
- Whether you use a VPN/Zscaler or another proxy

We’re escalating this case. Please share the results of the steps above and attach logs so we can localize the issue faster.
