Does this stop you from using Cursor

Yes - Cursor is unusable

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

Also this issue. Window 11
Just appears window with able to restart window / close / keep waiting

i changed beta - updated acess - to early access and now its not freezing. something happened with stable version.

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.

Yep experiencing this also.. I submitted a bug earlier today for it.
