Every time I go on a world while it's loading it always glitches then the game crashes, this issue started happening after the game updated and it only happens to ONE of my worlds

This issue only happens to only ONE of my worlds and it’s been doing this right after the game updated to the newest theam, I wouldn’t mind just deleting the world but I have A LOT of thing built in this world that I really do not want to delete cause it took me hours building the stuff in the world and personally I love minecraft and I been playing this game for a long time and I NEVER had a issue like this or even had issue so I’m hoping this issue can be fix so I can continue building in the world.
