Hi Vipan,
That new, complete log.txt helped a lot. At the very end is the sentence that tells us what went wrong:
--=={This application has crashed because of the plugin: X-Camera}==--
I recommend you try moving the X-Camera plugin to the desktop, then try X-Plane again and see if the crash goes away. If it does, you'll know that was the culprit and you could contact the creator to let them know.
