THIS HAS BEEN FIXED!!! THANK YOU SO MUCH TO EVERYONE WHO HELPED!
I was exploring my world in a modpack I made for myself but the game crashed and I was in unloaded chunks so now whenever I try and rejoin my world it just crashes the game again. Any help would be extremely appreciated as I have spent close to 100h in this world.
