Grok code is not working at all, it is not in a loop yet 2 secs into starting a task with grok code, it “thinks” its in a unrecoverabal loop.

req code: (Request ID: f76e42e0-c812-4c51-a3e5-7c2c081a2455)

Yes - Cursor is unusable

Same issue. Opening a new chat does not fix it. And this issue is not limited to Grok alone because even on auto the same thing happens. Getting this error since the past 1-2 weeks. No such error existed a couple months ago. This is the error which has made Cursor completely unusable.

I try to add timestamp like ‘current time: 2025-10-19 00:11:22‘ at the begin of prompt and retry. Still same errors. It will oupput something , then restart, and the final content is not complete. output is like bellow.

```html

    --h-toolbar-btn: 34px;
    --radius: 10px;
    --radius-sm: 8px;
  }
...

Let me reevaluate and take a different approach.
