KeyError: 'pdb_use_exclamation_mark' in Spyder

I just started my project this morning, which I left last evening. I was about to debug the code which was running yesterday evening without any changes.

I'm receiving this error: KeyError: 'pdb_use_exclamation_mark' This error is referencing to the beginning of the file where nothing has changed since I started my project. It looks like the following:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import os

And so on...

Any ideas on how to solve this? Haven't seen anything similar on the web, what might help.

(Spyder maintainer here) If you're using Anaconda, please close Spyder, open the Anaconda Prompt (on Windows) or a system terminal (on Linux or Mac) and run

conda install spyder-kernels=1.9.4

Then start Spyder again. That will fix your problem.
