I uploaded a single player world to my realm yesterday, and ever since then I have not been able to configure the settings on my realm so it is just stuck on that world. Whenever I try to click on 'Configure realm' on the bottom left words or tool icon, my entire game just crashes. Any and all help is appreciated! I just got the realm and wanted to play with friends because we r on summer break for a little while longer and we don't have much time after.
