Help ....WAMP64 - Internal Server Error, no way to start localhost (1 reply)

I'm using Wamp Server W10 from many years. Today it stopped to work with the Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

When I try to write on browser : localhost then the error comes out.
The wamp icon is green

I read and tried to make the apache modules - rewrite-module but the issue is still present and localhost don't work.
This is the apache log

I also don't find the .htaccess under c:\wamp directory but probably it's correct

I'm not a programmer and I don't understand the issue. I'm very worry because I got lot lot of things inside.

Have you got gently hints to fix it ?
Thanks
