Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
After updating Cursor a few days ago, Cursor has started crashing repeatedly on Ubuntu 24.04.4 LTS.
The crash occurs approximately every few minutes, most commonly while an Agent task is running. When the crash happens, Cursor displays:
The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’)
The issue began immediately after updating Cursor. Prior to the update, Cursor was stable on the same machine.
Steps to Reproduce
Open Cursor.
Open a project/workspace.
Start an Agent task (Auto model).
Continue working or allow the Agent to run.
After a few minutes, Cursor crashes with:
The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’)
Expected Behavior
Cursor should remain stable while running Agent tasks and normal editing workflows.
