The reason why I couldn't play any other worlds was farlanders, but I am still getting the chunk error. The link to my debug.log and latest.log is here, thank you so much.
Thank you for a reply, I've deleted my config folder a few times, and added any mods that I have removed prior to when my game started crashing. I've also updated countless mods, to no avail.
