Command crashes minecraft instand

1.10+
type this command:
/give @p skull 1 3 {display:

{Name:"Tobi"}

,SkullOwner:{Id:"ab530e1f-8f57-4a25-b628-5a2b4a5f7263",Properties:{textures:[

{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6IiJ9fX0="}

]}}}
and your Minecraft crashes instantly. In multiplayer you can kick all players with the command.

After a restart of minecraft other command crash too like /gamemode 1
It is not important what profile you are using, already tried to delete and create a new profile. We even restarted our server, but the game still crashes by typing /gamemode-commands! (Some other commands like /toggledownfall or /time still work perfectly though.) Ps: My Windows crashing because of the command.
