I'm trying to run a selenium test which should work just fine (hasn't changed and used to work) but I'm getting this strange error.

System.InvalidOperationException : unknown error: cannot determine loading status
from unknown error: missing or invalid 'entry.level'

What is this "missing or invalid 'entry.level'" error and how do I fix it?

I resolved this by updating my chrome driver to the latest version (v2.34 at the time of writing).

You can get the chromedriver here: https://sites.google.com/a/chromium.org/chromedriver/downloads

just download the .exe file then replace the chromedriver file in your project's selenium/bin folder.
