Upon loading my world an autosave is initiated, which crashes Minecraft returning me to the dashboard. Was working earlier today, started happening randomly after switching back from creative test world. Doesn't happen in any other save files, just this one. 

Tried creating a copy of the world to no luck. Tried immediately saving and exiting, which was successful without crashing, but upon loading the world again the same problem still exists.

Can provide footage but maximum file size is preventing me from uploading
