Arduino crash on start for 1.8.5 and 1.8.1 (debug information included)

Hi people,

My Arduino worked fine previously and I tried to work on MATLAB with Arduino. The add-on for MATLAB failed to work which uses Arduino 1.8.1 so I delete all the relevant stuff. Now I found that even my previously installed 1.8.5 version does not work where it shows initiating and preparing screen and close by itself after double click.
The result of arduino_debug is attached below. I have tried to uninstall and reinstall all different versions and redownload java but still getting the same error. Please help me with this.

Thank you.

p.s the first line of error says cloud server not running.
