Was playing non my Realm when I noticed my internet was moving at a snail's pace, so I restarted my computer. After, I found that every time I would try and load a world, the game would quit and give Java would find a fatal error. I tried re-installing Java, but this didn't help. So, I tried changing my profile's game directory. I found that this worked, briefly. I could now play the game normally, that is, until I changed anything in video settings. This would cause the game to crash a few minutes later loading up the profile again and trying to load a world would again crash the game. I have concluded that it is not a java error, as I do not experience this bug in 1.8.9, even with the same profile and world saves. Attached is the crash report, and if you need any additional information I would be very happy to give it to you. Please fix, <3
