Realm crashing every time I try to get on

Whenever I try to go on my realm, my game totally crashes. I'm not experiencing this issue on any other realms, servers, or worlds. I've tried logging out and back in, restarting my computer, and opening and closing my realm. When I click crash report, it says "A fatal error has been detected by the Java Runtime Environment" and a ton of coding/java stuff. I was just on a few hours ago, and I have no idea what could've happened in such a small amount of time. I go on my realm so much, so this is very irritating. Thank you for reading this and I hope it gets fixed soon!
