I couldn't turn off my PlayStation 4 so I had to turn it off from the PowerPoint. I then turned on my PS4 went through that bit. Then I loaded Minecraft back in. Did my Microsoft account, then went to my world's clicked on my best world. It then said "This World Is Corrupted. All Saved Files Will Be Deleted. It then Deletes my world altogether, I've tried methods to get my world back. But for the most part, they don't work. The world saved data to my PS4 is there.
