The Error is inside 'com/simibubi/create/content/contraptions/components/structureMovement/MovementBehaviour'. So the mod that caused this error is the create mod and the Java class MovementBehaviour. If you want to play your modpack, then you have a few things that you can do. You can post this error to the create mod author on his GitHub You can delete the mod you installed last You can install an older version of create or if you have downloaded this modpack from another person, then you can report this bug to this person or install an older version Or disable all mods except create and then enable one mod at a time and lunch minecraft again, until you find the incompatible mod. And maybe the easiest, but not the best method is to delete create and hope that it works.
