the problem was'nt in Sourcetree or Askpass, error raised when askpass try to use one of .dll file that worked with intel graphics(in my case intel 3000 hd).
for fixing I download intel graphic driver from intel(https://downloadcenter.intel.com/default.aspx) site and run then restart.
There was 'sourcetree.log' but there wasn't 'askpass.log' !!!
in sourcetree.log :
