In my game I suddenly found myself unable to break blocks using the left mouse button option, this only happens in my current world. When hand is empty or having a tool (pickaxe, axe, shovel, hoe) it cannot break down blocks, only attack.
Clicking the left button can only perform the attack option, and the right button still works perfectly.

The game is on survival mode and I have repeatedly reset the control options for mouse, even switching to touchscreen, nothing works.
