Unity 5.6.5f1 Project Crashes On Opening

First off, I think this has something to do with baking as the bottom right says "preparing bake" before crashing, anyway, on with the post.

So, I'm running 5.6.5f1 Pro, haven't updated recently and the project was created with this version, so nothing obvious has changed.
All my code in this project compiles without errors and didn't have any problems since today when I tried to open it and it crashes every single time, even if I Ctrl+N to make a new scene instantly after opening.

I have absolutely no idea what this is and I'm not getting any error codes and I'm not sure how to read the output logs, which I have attached, so I'm wondering if a Windows Update could have had anything to do with it.
