@MoshiBar
Please provide as much information as possible about what you were doing when this crash happened.

Do you have any KubeJS scripting in use. If so, please attach.

Was this caused by a custom item? See previous question.

Do you have a latest.log, and debug.log? If so, please attach.

I had the same issue, crash log however was empty, tested it twice. I was eating bread after updating all of the kubejs mods and create, and also updating to the newest forge version to accommodate the create update.
