Ralsei

Randomly an hour ago, a single player world I created two days ago randomly crashed and now when I try to load my world it infinitely loads and is stuck at 100%. It does this for new worlds too. Without my mods, my corrupted world has removed all of my building near spawn but nowhere else in the world. Any help is appreciated, I'm at my wits end. I've tried googling and watching YouTube videos to help but nothing works. Please, I'm desperate. Sorry if this isn't the right topic. Latest.log
