Error – White Page Backend

Hello,
after having configured AAM for all the roles, some of them accessing from the backend will return a blank page.
I just hid some menu items and created the aam_show_toolbar functionality.
After this, some roles such as: Author and Publisher are no longer able to see the wordpress backend in fact after logging in they are returned a blank page.

I followed your guide, I deactivated the plugin and the problem continues, I reset the AAM settings plugin and the problem continues, I reinstalled as you indicate in the guide and the problem is always there.

These roles can no longer log in.
How do you fix this now?

Thank you
