Hey, thanks for the report. Let’s quickly narrow down the cause.
Please check:
- 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
- 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’)

- 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-extensionsand 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.
