Back Button Unresponsive, Unable to Return to Main Menu

There is a critical bug where the back navigation stops working completely. This issue affects both the on-screen back button within the game's interface and the device's system back button (or gesture).

When this happens, I become stuck on the current screen (like the settings menu, marketplace, or world screen) and cannot navigate back to the main menu. The only way to exit the screen is to completely force-close the Minecraft application and restart it.

Expected Result: Pressing the back button should take me to the previous screen or the main menu.

Actual Result: Pressing the back button does nothing, trapping me on the current screen.
