CONTROLS ARE ALL OVER THE PLACE!!!!!

i can't hit any mob in real time, when i hit i have huuge delay, vindicator slained me twice, because i couldn't kill him. elytra doesn't work either. i already fell into void because elytra didn't want to fly. i have good configuration, aind, every time i enter the world, i have to wait 10-20 seconds for world even start rendering. and, every block i break reapears for the moment and then breaks
