Minecraft Bedrock Save and Quit freezes

Minecraft will not save. When I Save and Quit Game the loading screen that says “Saving World” does not go away. Even if I leave it open for hours or days. It never completes saving. I have to force close the game. Also, Minecraft’s auto save feature isn’t working. It does not auto save at all anymore. I never messed with any settings. Minecraft just refuses to save.
