Well that's certainly a new one. I know the stream with all the confetti and rainbow text and stuff can cause lag, which is why I put in the stream performance mode in the first place, but I've never heard of it actually crashing the game. To be honest, I have no idea what exactly's caused that, but I'm glad stream performance mode fixed it.
Also, I appreciate how much detail you put into your description of the error. It's a shame I only saw it after you had already found a fix, but it's much better than people saying "The game crashes sometimes" or whatever. I hope you enjoy the rest of it.
