webconfig error in IIS 10.0 HTTP Error 500.19 - Internal Server Error

got this problem after deploying my web package to IIS:

HTTP Error 500.19 - Internal Server Error the requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information: Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x8007000d Config Error
Config File \?\C:\inetpub\wwwroot\LLWR\web.config Requested URL http://localhost:80/LLWR Physical Path C:\inetpub\wwwroot\LLWR Logon Method Not yet determined Logon User Not yet determined Config Source: -1: 0:

I have analysed all the related site, and Installed IIS URL Rewrite Module2

I can understand that my webconfig file is the error. but i could'nt find which one I'm missing.

Actually I'm using webapi is my serverside and angularjs is frontend

Its my webconfig file
