Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report and the detailed stack trace. That really helps.

The infinite recursion in Lv points to a stack overflow in the sandbox code. A couple things to narrow this down:

  1. Can you try running Cursor with extensions disabled? Run cursor --disable-extensions in your terminal and see if it still hangs in agent/plan mode.

  2. How big is your project, roughly? About how many files and folders?

  3. Next time it hangs, can you copy the Request ID from the chat? Click the three dots in the top right of the chat panel, then Copy Request ID.

Let me know what you find.
