World was working perfectly fine yesterday.

When I went to open the world to day after getting past the square loading screen my instant of the game closed and I was given a crash box that allowed me to close the box or open the crash report.

Tried again multiple times and got the same issue. Can load all the other worlds I have, just not this specific one. Would really care to much if it was a survival world but it's a hardcore world I have made significant progress on.
