Because I need to use MySQL Workbench for college, I left port 3306 pro server for Workbench and switched to XAMPP for 3307 as the guy Suman Kotagiri said in this forum link
When I started the MySQL module in XAMPP I thought I might make a mistake, but no, it turned green and said its status was 'running'. But when I click admin, this window appears in phpmyadmin:
There are not many questions exactly about it so it's a little vague about what might be happening. Is it possible to be experiencing some workbench conflict with XAMPP anyway? I turned off the server through MySQL Notifier because I thought it would be a problem to have two servers connected at the same time but it did not help me 100% to get it right.
