Yey Update 1.9 is here, and I crash EVERY TIME!

I just downloaded the 1.9 update and went to play it.
I launched just fine, Everything's good. Going to load my Minecraft Realm and once Its finishes loading, the game crashes immediately. I tried again, and again.
Changed the dumps of Ram on Minecraft, and still crashes.
Unistalled Minecraft(deleted all remaining files, appdata included).
Installed Minecrfat again, and it still crashes.
Deleted all Java on my pc. and installed the latest, and it still crashes.

HOW THE HELL!? AM I... going to solve this?

Help?... anyone? I'll attatch the bug report.
