@MojangSupport Good news, Bedrock isn't broken. Bad news? My world is probably corrupted, which would explain the freezing and blue screens. Considering Minecraft is always being updated, and knowing other people put hours of work into their worlds, is there a way to fix this?

Unfortunately, at this time, there are no ways to fix corrupt worlds from our end. If you don't have it stored in a Realm and have a backup of the World you may not be able to fix it. ^TK

That's what I feared. Well, is copying a world the same as backing up a world? (Before it corrupts obviously.) If so, I guess I'll have to do that from now on. This is my first time dealing with a corrupted world.
