I downloaded a Minecraft Bedrock Edition server on my computer, I started it, and it was fine. I have been normal for the past few months, but today I restarted the server, but I got an error when I started yesterday (2022.1.7) that I lost 2 files in my archive, and it always started like this after that. Today (2022.1.8) started without error, but the area blocks outside the area block I was in disappeared. I haven't touched any files, but what's the matter

Due to the file size, I uploaded to Google
