Created a world in Hard mode, used cheats to advance the days to bring up a 3.50 difficulty. Eventually encountered a series of game crashes, determining the cause to be around Drowned mobs using Tridents. I couldn't tell if I was hit, but as I set the difficulty to Peaceful, the crashing ceased.

As such, this game-crashing bug seems to revolve around damage calculation with mob-thrown Tridents towards players, or the Drowned mob in general.

No precise screenshot could be acquired.
