The New Launcher keeps crushing.

Since the new update of 1.10.2, the Forge Updated too, Which caused minor issues, I tried to play first in 1.8 then when I joined Realms or Singular player or Multiplayer and the servers in it I crashed every time I press the join button, so I tried the latest version (1.11.2) didn't work and I tried every version still crashes with no respond, Please Mojang tell me what is the problem and the solution to it.
Thanks,
