DS not responding for 1 specific previous saved file

qert

This current file i have been working on since morning and i have saved and open many times before however since the last save which i close DS 2 hours ago, the file will not load properly and doesn't show up on the viewport, instead it gives (not responding) for nearly an hour when loading that saved file.

My other files loads just fine and it only affects my latest work.
