I once had a similar problem to yours. I"m not 100% certain it will work, but try to lower your render distance. Apparently there is/was some kind of bug which made my minecraft crash when I tried to load a world

Good luck!

Do you like to play modpacks? Try my modpack A.M.I.C

Nothing to do with render distance, is something blocking minecraft from using the loopback address(127.0.0.1)
