      Returns whether uncaught exceptions in main thread should crash the game instead of logging and ignoring them.
      Returns:
      whether uncaught exceptions in main thread should crash the game instead of logging and ignoring them
      See Also:
      API Note:
      This only affects the processing on the main thread done by calling methods in NetworkThreadUtils. Uncaught exceptions in other threads or processing in the main thread using the client.execute(() -> {}) code will be unaffected, and always gets logged without crashing.
      Implementation Note:
      This is true by default.
