Cursor not responding on Agent mode

Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m experiencing an issue in Cursor where the application becomes unresponsive (“not responding”) after applying changes while in Agent mode. The error occurs consistently right after modifications are made, requiring me to force-quit and restart the application. This disrupts the workflow and prevents effective use of the Agent functionality.

Steps to Reproduce

Open Cursor and ensure you’re signed in.
Enable Agent Mode (e.g., by clicking the Agent button or using the command palette).
Make a code change—either by accepting an AI suggestion, editing code manually, or triggering an agent action (e.g., “Refactor this function”).
Apply or confirm the change.
Observe that Cursor immediately becomes unresponsive (“Not Responding” in the title bar on Windows),

Hi team,

I’m confirming this critical issue is affecting more than one user. I’m on Cursor v1.7.54 (Windows) and experience an immediate freeze (“Not Responding”) every time the Agent modifies or creates a file—requiring a force quit.

Another user has already reported the same problem, and I’ve also submitted a bug report. Since this completely breaks Agent Mode, I’d appreciate urgent attention.

Thanks for your support!

The team are busy working on v2.0 (early access), so it’s possible this issue is already fixed for you.

You can try it here, and the installer to downgrade back to 1.7.54 is also available if you want to: https://downloadcursor.app

Hi there i just want to inform you that there is a workaround for this issue. You can find the problematic line in settings.json "workbench.editor.showTabs": "single". When none or multiple, I don’t have any issue.
The workaround was finded in this bug report: Cursor freezes after AI-edit tool call — resolved by removing 'showTabs: single'

it worked for me

Hey, thanks for the report. This is a known bug and it’s already been escalated to the engineering team.

Workaround: In your settings.json, change "workbench.editor.showTabs": "single" to ”multiple" or ”none", or remove that line.

This should stop the freezing right away. Full details and discussion: Cursor freezes after AI-edit tool call — resolved by removing 'showTabs: single'
