When I Log into my world, everything acts fine for a couple of seconds. Then it starts to lag, it stops lagging, then it crashes. I dont have cheats on, theres no command blocks or any farms on that could lag my game, it just crashes without any reason. This started to happen yesterday, my brother was on my local multiplayer world (the same world shown in the video) and it randomly crashed while I was afk. This is now happening everytime I go on the world and it sucks cause I have ~50 hours of playtime on this world.
