Why has Cursor been responding extremely slowly over the past two days?

Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

When I use Cursor to call the Opus 4.6 model, the response is extremely, extremely, extremely slow.
Even a very simple question now takes more than 20 minutes to process. It used to respond smoothly and fluently before. What is causing this?
