When continuously holding down the build button in the game, it becomes impossible to swap items in the inventory during this state. The glitch occurs when the player looks at the nearest block, enabling the use of the build button repeatedly without releasing it. Upon trying to swap items, either a malfunction occurs, or items get rapidly and automatically swapped between slots, creating an unintended and erratic item swapping behavior. 

 Steps to Reproduce:

 1. Begin holding down the build button in the game to enable continuous building mode.

 2. Look at the nearest block, allowing for repeated usage of the build button without releasing it.

 3. Attempt to swap items in the inventory while the build button is continuously held down.

 Expected Result:

 When holding down the build button, the player should still be able to swap items in the inventory smoothly and without any unexpected behavior. Item swapping should function as normal regardless of the build button being continuously held.

 Observed Result:

 Upon following the steps mentioned, attempting to swap items during continuous build mode results in a glitch where items may not swap as intended. Alternatively, items may be rapidly and automatically swapped between slots without player input, leading to an unpredictable item swapping behavior.
