After playing a while on a vanilla Bedrock Server (Linux), my player got stuck in some water and disconnected. After that, I am unable to resume play on any client, Windows 10, Android 8 or custom Linux client (mcpelauncher).
Upon login, I am unable to see any blocks (light blue screen, see attachment). Other players found my player and described it as being transparent and unresponsive. I cannot move the player, nor access inventory or perform any other actions.
I tried issuing the /kill and /tp console commands which appear to work (killing/respawning and moving my players position), but nothing changes with the player's broken state. This was the case for both the Android and Windows 10 clients. After a while, both clients hang and become unresponsive. On Windows, the entire machine hangs with excessive disk I/O and must eventually be hard rebooted.
At one point I was attached to the server and saw the output below in the log. The server was running in a Docker container.

As it stands, I'm unable to play in this world at all now, and I have no more ideas for how to remedy the situation.
