This ticket is invalid as it relates to a modded or 3rd party client/server.

Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.
Any plugin issues need to be addressed to the plugin creator.

It is n minecraft realms though?!

Unless you can reproduce this in vanilla this is a mod issue.

so it might be because i have optifine and better sprint?

help please

Sorry, modded clients are not supported on this bug tracker.

So it could be because i have mods installed?

I can confirm this. I'm using the same computer with no mods installed and when I'm trying to join, the world crashes.
