World load crash on a specific world

I've started playing ever since windows 10 pc was free, and gotten the free code recently.
Me and my friends have been playing on a world together for a week or more, and now the game crashes whenever i attempt to load it. I try seeing if its every world, but a new world works. Can you please see if this is fixable, as it would be hours of work wasted. Thank you.

1 screenshot is the load before the crash (the not fully loaded one). Most times, it crashes before the world fully loads, in others, it loads and then crashes.

The next 2 (fully loaded bar and screenshot of world) is me loading a new world successfully.
