Single player world lags every time the game autosaves. I can't interact with anything. Can't open doors or chests, can't exit a boat, mined blocks don't drop as an item and they come back when game stops saving. Mobs also freeze. Doesn't affect FPS as far as I can tell. Tried giving the game more RAM, tried uninstalling and re-installing minecraft, tried turning PC off and on. My internet is good. My graphics driver is updated. Hard drive has plenty of space and no problems. This happens in vanilla and I also tried with a fabric loader. Same results. Found a few more people on Reddit with the same exact problem. (All of them seem to be from northern europe so I don't know if that's a coincidence or if it has something to do with this problem.)
