I only started playing Minecraft a short time ago with my son, so I don't know much about it's configuration options. With the set up I'm playing on, everything works fine, however whenever I join his world I get multiple crashes. Here is a pastebin link to the latest log https://pastebin.com/FuzNMqGM
Every log file looks more or less the same for this crash. I don't change anything between playing his LAN world and my own single player world. The in game performance is fine right up to the crash.
Any suggestions as to what I can do to stop these crashes, or at least make them less frequent?
