D:\Program Files (x86)\PHP\v7.0\php-cgi.exe - The FastCGI process exited unexpectedly

I have php website on azure in free tier.Everything works well except sqlite3 which requires the sqlite3 dll.

I downloaded the dll and did what is said here:

Here is the full error:

HTTP Error 500.0 - Internal Server Error
D:\Program Files (x86)\PHP\v7.0\php-cgi.exe - The FastCGI process exited unexpectedly

After that i get this error, obviously i do not have D:\Program Files (x86)\PHP\v7.0\php-cgi.exe in azure websites.

I do not have that path mapped anywhere in my code !

i have in the azure php error log.txt
