Help my help my Minecraft Items are broken?

I have a problem, and my Minecraft items are broken in that way because I can't treat them with a certain key combination as normal.

What can't be wrong:

I have already completely reset my control and tried with new keyboard shortcuts.

To say exactly what is broken z.b. If I want to do items from the inventory or from the chest to the other one, I can't do that as usual with the snake key (shift), but have to put them individually in the chest. And if I now put them individually in the chest I can on z.b. No more 20 pork and the rest stays in my hand, but has to divide them until there are exactly 64. In addition, sometimes my creative fly or normal build or dismantle suddenly turns solid, so it breaks down all the way down or builds up point and I do not want that, I've been trying to sort of out but I have not found anything and I'm really desperate, It does not matter if it's creative or survival.

In short, my items can no longer be stacked and quickly pushed from A to B by the sneak button. This error happened after the latest update, in Minecraft version 1.13.2. And creatively fly or dismantle build up sometimes without reason consistently after I've built, mined or flown.

Well, first of all, this is just a game, so you should not do such a riot. Second, have you ever looked at Minecraft internally, whether there perhaps the control was adjusted?

What is Minecraft internally, and how can they help me?
