Me and my brother were playing Minecraft bedrock when my game became unresponsive. I reset my computer and went back in. upon logging back in I found that my world was missing. I checked every file, the recycling bin, and even reset MC. The application basically just refused to acknowledge the even existence of the world. I need help soon on how to find it, because this world contained months of work, and included content needed for my YouTube channel.
