title: google colab errors - can't open anything
body: <p>I was using Google Colab to do some python practice. I have quite a few notebooks with homework and notes in them. All of sudden I can't save anything or even open a notebook I saved earlier. These are the errors I get.</p>
  
  <pre><code>Notebook loading error
  There was an error loading this notebook. Ensure that the file is accessible and try again.
  Unexpected token S in JSON at position 0

  <p>I've disabled all extensions, logged out, deleted cookies, tried incognito, tried sharing and using another account but still can't download any notebook, restarted runtime. I can't even create a new notebook without the first error happening. It happens in any google account I try.</p>
  
  <p>I'm out of ideas and tried anything I've found on here that pertains to it.</p>
