I woke up this morning unable to load my project because of the same crash.
I’ve been working on this project for a few weeks but now it looks like my day is ruined and I haven’t even had my coffee yet. 
Just bumping to see if anyone figured out any other type of fix before i go in and start deleting stuff oe by one.
Also to note that I did start off the project with world partition enabled, but after having some other issues with it, I disabled it in the Project Settings but it looks like that doesn’t get rid of it.
