I logged onto the launcher to test out the new snapshot for Minecraft 1.9. It finished downloading and the launcher disappeared and Minecraft came up, but instead of working and being playable, it instead crashes instantly. I don't have any mods or recourse packs on, and all of the other versions work fine. Help?
Try to reopen the launcher, Dinnerbone suggests restaring it.
"If it immediately crashes, restart the launcher!"
