All menu links from admin dashboard takes me to a 404 on local project

[imahh17]

First of all, I am quite new to Prestashop.

After consulting several threads on this forum and on the Internet in general, I have not found a solution to my problem:

I have installed on my localhost MacOS this Prestashop project that has been running for years now and requires an update. The current version is: 1.7.8.8.8

I have set it up using Herd, whose server is a Ngingx, not Apache.

After mounting it, the whole front end looks fine. But when I go into the admin panel and try to use the menu links, they all lead to a 404, I can't access Products, or even Site Preferences.

Things I have tried: 
-Delete the .htaccess from the admin folder.
-Change the permissions of all the folders in the project to 755 and 644.
-Check that the database configuration is correct, in the front end all the products are shown correctly.
-Activate the DEBUG mode, which apparently does not throw errors.

The only thing that has achieved a small change:
-I have disabled Friendly URLs from the database:
UPDATE `ps_configuration` SET `value` = '0' WHERE `name` = 'PS_REWRITING_SETTINGS'; 
This makes 404 no longer appear when trying to enter the links, but I get this error:
[Debug] This page has moved
Please use the following URL instead:
If I try to enter with the suggested URL, it always takes me to the home page.

I've had this for 5 hours and I don't know what else to do... In production the access to these links in the admin menu works.
