them module not working in v16 

ir.ui.menu model and create an ir.rule for it, but there's an issue with how Odoo handles security rules for this particular model.

donc: 

1- delete rule: 

<record id="restrict_menu_user" model="ir.rule"> <field name="name">Restrict Menu from Users</field> <field ref="model_ir_ui_menu" name="model_id"/> <field name="domain_force">[('restrict_user_ids', 'not in', [user.id])]</field> 

</record>

2- you should override the _filter_visible_menus method of the menu model to implement your restriction logic

@api.model
    def _filter_visible_menus(self, menus):
        """ Override to filter out menus restricted for current user """
        menus = super(RestrictMenu, self)._filter_visible_menus(menus)
        
        if self.env.user.has_group('base.group_system'):
            return menus  # Superuser can see all menus
            
        # Filter out menus where current user is in restrict_user_ids
        menu_ids = menus.ids
        restricted_menu_ids = self.search([
            ('id', 'in', menu_ids),
            ('restrict_user_ids', 'in', [self.env.user.id])
        ]).ids
        
        return menus.filtered(lambda m: m.id not in restricted_menu_ids)

This is really a good module to hide any menu from specific users. But I suggest for improvement, please remove the printed vals and res in the HideMenuUser class that is inherited from res.users, especially in the:

print('hi', vals)

in line 35 inside the create method.

When we create a new res.users record it will be logging out in the log, including the email or login field, and it will also show the password if we filled the password directly when we create res.users.

So, I think it will be risky for our Odoo security.

Thanks,
