Random Deaths

While playing Minecraft Bedrock on my win10 PC, I have inexplicably died twice now. I believe it may be something related to being AFK, but I'm not sure. The first time it happened, I had been AFK for a few minutes, then came back to the game and resumed playing, only to be stopped by death. The death message was "[Player] died". The second time, it occured while I was AFK. I came back to the death screen with the same exact death message. I didn't lose anything of any importance either time except for my almost 100 total levels of experience. If you need any further information, please ask.
