Advance statement: I didn't install any behaviour package that can freeze the world, and I didn't use any third-party mod to freeze the world. This is the bug.

Fault description: When I was playing the《Minecraft》bedrock edition, I accidentally pressed the home button on the iPad, which caused Minecraft to enter the multitask interface, I return to the desktop. However, when I re-entered the game, everything was still. The blocks did not break the particles and place sound effects. The interactive blocks could not be used, such as furnace. the entity could not attack, but there were sound effects from the entity, such as the sound of chickens. Some incomplete blocks will still leave hitboxes, such as doors and steps.
