There's a bug in Minecraft 1.10.1 that crashes your game when connecting to servers.
See MC-103981 and MC-103978 for more info.

In the meantime, you can safely downgrade to 1.10 until a proper fix is released.
To change your game to a different version, start the launcher. Select Edit Profile.
In the "Use Version" dropdown menu, select the game version you want. Then click Save Profile.
