Have been playing Minecraft dungeons for the past 2 weeks or so. The game has been freezing multiple times per day randomly during my play sessions, resulting in me having to shut the game down and restart it, losing all my progress in the process of a dungeon run.

I cannot identify any specific scenarios where the game would crash, as it seems to be completely random. They usually occur in the middle of a longer dungeon session, and occur when we are fighting mobs, travelling to a different instance. No crashes occurred while we were at camp or looking at the map. 

I have tried putting my switch to sleep and opening it back up again but it still remains frozen.
