Game keep crashing for no reason

My game runs on steam, but today I suddently found I it keep crashing with no error code or any warning. I played in the morning and when I came home at night it doesn’t work.
I’ve tried:

  1. use the EAC repair - doesn’t fix
  2. use steam verify integrity - no error
  3. reboot - doesn’t work
  4. reinstall the game - doesn’t work
  5. run game in gaijin launcher - can play with out EAC
  6. check background applications - still doesn’t work

I can upload the game log ( I cant read it since its .clog)
