I went on my realms server to play with two friends and my sister, but the realms the world timed out around my house, I downloaded the world to see if it worked but it was messed up and after awhile frozen. After awhile it gave a crash report. My two friends can play on the world on realms ,but me and my sister will time out and my my other friends time out as well, but they can rejoin fine. Also my other realm worlds work fine.

I have no idea how this started happening but it started when i got my new laptop and minecraft had a hard time installing but I have minecraft working, it also was after we spawned a lot of mobs when messing around which are all gone. When loading the chunks around my tower the world times out and then I can't get on with out it timing out, I've backed the world up in realms, and had my friend who still can play remove all enities around the area that is timing out but the problem is still there, and I can't find out how to fix it.
