Loading 1.14 or 1.14.1 crashes the game 90% through the progress bar

My screen shots show that the progress bar is only at 5%. I've seen this issue multiple times and they all get marked with invalid. I genuinely can't play mine craft on any of my worlds cause they're all 1.14+. Please fix this, I'm really starting to feel like the people at Mojang don't care. I also sometimes need to force quit the game through the task manager
