I’m experiencing the same issue. It started occurring after updating to the latest version.

I also experience agent mode hangs on thinking, modifying, concluding, mostly it worked under 10% of the actual tasks and need to stop it manually and tell him to resume, and redo this a couple of times to get the job done. It is very annoying and like making the daily productivity 500% slower

Hi all, thanks for the reports.

If you are on Early Access, and need an immediate fix, please use Download · Cursor to redownload our latest stable release while we resolve this.

For anyone who can reliably trigger this issue, can you please run Developer: Toggle Developer Tools and check the Console tab for any errors that show up when the Agent tries to edit a file.

Also, please share your Cursor version and OS too - thanks!

I did the exact opposite. I’ve downgraded to v1.6 for now to move forward as the latest version was where I was facing the issue.

It appears to be related to this setting for me:

"workbench.editor.showTabs": "single"

Turning that off in the settings fixes it.
