I recently upgraded my engine to 5.5.3 and switched my main World Partition level to use the new Static Lighting for World Partition levels. The baking process works totally fine and the level plays well. But the problem is that when I close the editor and re-open it and try to hit play on the level again, I get this error and the editor closes shortly after:

Crash in runnable thread IoDispatcher
This results in me needing to re-open the editor and bake the lighting again before I can play the level without crashing.
This is undesirable because it causes 300+ changes to the git repo each time.
Has anyone else encountered this one before?
