Hey, doing the same, self-hosted using XAMPP on Windows, however, the Rewrite module comes enabled by default on Apache, and the htaccess file worked right away, so I do not know how may we fix this. You may want to try reinstalling XAMPP on another hard drive and see if the issue goes away (after ofc moving the old htdocs folder to the new XAMPP install and importing the database back). I'll also add you on Discord because I see you speak Spanish, and so do I.
