Game does not reopen if it stays in the background

By closing a world and minimizing the game, by reopening it it will not leave the black screen

How to produce

1. open any world;
2. get out of the open world;
3. minimize the game;
4. reopen the game.

What happens?
the game is on black screen and does not load.

What's supposed to happen?
the game should reopen normally.

Note to be made:
If the same process is performed above, however, closing the world screen (and going to the main one) the game will reopen normally. The error is only if the worlds screen is open.
