How do you find out which stupid plugin is creating this error, the log is showing thousands of useless line except what is need like what exactly cause a crash

There's usually a backtrace at the bottom of the log.  Failing that, you can remove all plugins, run X-Plane, then add the plugins, 1 at a time, reloading X-Plane each time, until it crashes.

It only happens in some area, so far it is in the KIND and KLAS that it is happening, and it could be a few second after the game started, then again a few hours after, but it is always happen quickly if I am leaving from those airport than when I am trying to fly to those airport
