Unity Crashes on Scene Open

Unity Engine
1

I opened Unity today and did some work on the current scene, and tried to open another scene to do some other stuff, so this was the first time I had attempted to switch scenes this session, but when I went to open another scene, I get this error:
3125853--236774--UNITYERROR.png
And then Unity closes itself.

After a little Googling I decided to clear my 4GB GI cache, but no dice.
I have also tried switching my layout to a default one, still nothing.

Still unsure of what is causing this, anyone have any ideas?

So, I thought I’d leave it for a few days, and not I get this:
3130520--237141--UNITYERROR2.png
I have tried renaming the library folder so it has to make another one, but still problem.

I also reinstalled Unity and restored my project from a backup, but still thing once again.

Is this Unity doing this (5.6.2f1 (project upgraded from 5.5.1f1)) or is there something in my project that is damaged, as the error suggests?

& is there any way of fixing it so I can get some work done?

Bump?
