Maybe bug with java 16 but I am not sure.

When I open the game and I go to the world selection, the play buttons on the left of each world are bugged. And in the inventory, to grab an item, I have to hold the left button, move the mouse to the desired place and release the left button. And the "shift-click" doesn't work in the inventory.

The reason because I think it is a launcher bug and not a version bug in becouse it happens in all versions of te game. 

I think it happens because now I need java 16 and I think I have java 8, but the launcher says that it updates automatically. I tried to reinstall the launcher but it doesn't work.

Help me please.
