Error: Could not find or load main class net.minecraft.client.main.Main

Played Minecraft 1.9 24 hours ago.
Tried playing Minecraft again today.
Prompted ''Ready to download & play Minecraft 1.9''

When i click on play its starts downloading and then the game output says:
Error: Could not find or load main class net.minecraft.client.main.Main

And when i press play again its boots up Minecraft 1.8.9
When i close the launcher and try again it will do the same thing, first the error then it boots 1.8.9

This is most likely the cause:
