When attempting to install new extensions I got this error consistently:

Unterminated string in JSON at position 8192 (line 1 column 8193): Error: Scanning: Unterminated string in JSON at position 8192 (line 1 column 8193)

And other JSON related errors, every single one of which included the number 8192 (8kb)

Steps to Reproduce

  1. Install Cursor
  2. Import from VSCode (ideally an instance with lots of extensions, i had around 50)
  3. Attempt to install any extension.
  4. View logs
