How to disable Build ans Settings for User?

I need to disable Build and Setting for Users.
I need use only Education module not more.

Go to Users → User → Select User → Allow Module and uncheck the modules you don’t want the user to see. you can also create a module profile and set this up. you can then apply the module profile to each user accordingly.

I know. But I use there only

Build and Settings belong to Core. Uncheck Core to remove the module from users access

I know. But When I doing it, and relogin in User account I have nothing, also Education module hidden and other.

any ideas?

what Roles have you given that user ?

Employer and Instructor.

Looks correct , in the modules , remove core and enable desk, see if that helps.

If I enable only Desk I have the similiar situation…
