Describe the Bug

Description

Cursor becomes unresponsive and crashes when typing @ commands (e.g., @permissions) that trigger the suggestion/autocomplete menu. The window freezes and shows a “The window is not responding” dialog.

Steps to Reproduce

Actual Behavior

  • Cursor freezes immediately when the suggestion menu appears
  • Window becomes unresponsive
  • System dialog prompts to “Reopen”, “Close”, or “Keep Waiting”
  • Application crashes or requires force quit

Environment

  • Cursor Version: Latest version (please check: Cursor → About Cursor)
  • OS: macOS
  • OS Version: 26.1
  • File Type: TypeScript/JavaScript files (.ts, .tsx)
  • File Size: [If relevant]

Additional Context

  • This occurs specifically when typing @ commands that trigger autocomplete
  • The suggestion menu appears but the application freezes before interaction
  • Issue persists after restarting Cursor
  • No error messages in console before the freeze
  • Issue started occurring after updating to the latest Cursor version

Screenshots

[Attach screenshots showing:

  1. The suggestion menu appearing
  2. The “window is not responding” dialog]

Workaround

  • Avoid typing @ commands
  • Use alternative methods to access features
  • Restart Cursor after each freeze

Priority

High - Application becomes unusable when using @ command feature

Steps to Reproduce

  1. Open a file in Cursor (e.g., permissions.ts)
  2. Type @permissions (or any @ command)
  3. Wait for the suggestion menu to appear
  4. Cursor freezes and becomes unresponsive
  5. A dialog appears: “The window is not responding”

Hey, thanks for the report. Let’s gather diagnostic information to identify the cause of this freeze.

Please try these steps:

Test without extensions: Run cursor --disable-extensions from Terminal and see if the @ command freeze still happens.

Before the next freeze, capture:

  • Process Explorer: Ctrl+Shift+P → “Developer: Open Process Explorer” (screenshot any high CPU/memory processes)
  • Console: Help → Toggle Developer Tools → Console tab (share any errors)
  • Quick fix: Close all open tabs and clear chat history if you have long conversations

Could you also share:

  • How many files/tabs do you typically have open?
  • Project size (if it’s a large codebase)?

Let me know what you find.
