Thanks for your reply!
Yes, it happens with several of my projects.
The only step I am taking is trying to change the world origin. It always works, but seemingly just one time.
Just the game crashes, the editor stays open.
The message log doesn’t show anything most of the time, but sometimes there is a “failed to get player pawn” error.
