Game Crahes when launching Minecraft

I have selected my snapshot water version (1.13 pre-release) and when I try to launch it with the Minecraft launcher it is loading for a split second and saying '' An unexpected issue has occurred and the game crashed. We're sorry for any inconvenience  '' this is titled GAME CRASH. I have tried restarting it several times even restarting my computer but it is there. I am biting my nails until I get this fixed
