I was attempting to do an Ominous Trial, and one of the potions that spawn during the trial landed on a Breeze before it died and it crashed my game.

I then went into creative and tested again if it was the Breeze dying that caused the game to crash and it was indeed the problem. You don't even need to be in an Ominous Trial event, the oozing Breeze will still crash your game either way.
 
 
Below is my crash report from the crash.
