I'm having the same exception.
At the instant I broke a certain Stone block in my CSP world (I've broken thousands of blocks before), it said Saving chunks and the error report flashed for about 0.05 seconds and then the white screen. From then on, whenever I load the world, it starts with Loading, then Simulating the world a bit, then saving chunks and the white crash report. It doesn't appear to be totally crashed because when I press the close button, it closes after about one minute. I have no trouble loading and playing my other CSP worlds.
Same error. Here's a longer error report:
