It started after i was sorting items in my chests on my main survival world, at the time i did have another player in the game with me,but the problem still occurs even if it’s single player or multiplayer, but when i would open the chest it would take a very long time to open and items where not going in. Then after that i tried breaking blocks they would just disappear and the block would then appear on the ground about 5 seconds after i have broke it. The block that was broken would then glitch up and down and would not let me pick it up. 

When i tried to go into the nether it would not let me in but then it would spawn tons in mobs inside of my house but they would not attack me. But I could also not kill mobs of any type.

When i tried to eat on low hunger i would eat the food but it would not fill up my hunger bar. When my hunger bar ran out it would not kill me whatsoever. Also when i ran out of bubbles underwater it would not kill me. 

Ive tried restarting my minecraft and nintendo switch and making a duplicate of the world but nothing will seem to work. I have never occurred this problem before.
