Was in the middle of a trial chamber doing a trial then the game suddenly crashed. Anytime I try to load into the world now it gets to the loading world screen and then crashes with the same error every time.

The error screen says:
"The game crashed whilst ticking entity

Error: java.lang.ClassFormatError: Method a in class brs$a has illegal modifiers: 0x8

Exit Code: -1"

I have a crash report too, I remember something like you don't want to share it with everybody (correct me if im wrong because I probably am) because it contains sensitive information but i'm probably thinking of something else, so I won't include it unless asked just to be safe
