This Bug (Input Delay) When Entering Different Dimension will cause keyboard inputs to happen late: For Example You enter the Nether And Press "s" to exit your portal, the movement Registers 6 seconds later so when the 6 seconds happens you walk backwards for 6 seconds your other movements register having you barrel into the lava ocean where your diamonds iron and axolotl will burn. It Only happens if you have multiplayer on (I think) (It doesn't Matter If Someone else is on the same world as you) (Doesn't Happen with mouse)
