Stevie gets frozen in space and time after entering nether.

After teleporting into nether, chunks do not load.
I still can move camera freely, I can switch inventory. Yet I'm unable to move, change gamemode and items in my hand don't move with my view, they seem to, get frozen in one position.

Also I can not quit a game cause it crash, and when I reload game, I'm ending in front of nether portal, in overworld, just before entering it.

I seem to have problem with finding similar issue, so I'm sorry If it is a duplicate.
