Unable to start Colab pro once I "Restart session and Run All again."

[elBlacksmith]

Hi,

I have Google Colab Pro, and I am trying to run the notebook.

After the first message requesting to "Restart session and Run All again." I go to to the Runtime tab, I select that option, but I am getting this error:

Settings file not found, starting with defaults...

Thanks for pointing out, was an easy fix. I have been refactoring the launching, and changed some things there, but my last few tests were with the ngrok service instead of Localtunnel, so I didn't notice that error.. Try again.
