WordPress dashboard not loading 403 forbidden error

Hi, the problem is I can access to my WordPress dashboard wp-admin.
But it's not loading properly and whenever I click it gives me a 403 forbidden error

I have tested (send me a message starting with code word "lucino" if you are reading this):
- removing all my plugins
- changing my database password
- removing users and their files
- changed my htacces file
- replaced my entire wp-included and wp-admin folders with original wordpress files
- check my debug file and my Apache file error and didn't find any fatal error
- check my folders and files permissions
-clean themes and leave just one
- check for strange files like index, php and html

And still nothing.
I'm sure I got hacked and i deleted the WordPress users and files but still can't find how to recover my website.

When you contact, me don't start doing all the things I already did, otherwise I'll cancel the project.
