routes.rb section:

You are setting up that route with a constraint

%w[profile_photo cover_photo].each do |croppable_image_name|
  resrources
    ...
    constraints: { name: croppable_image_name }
  end
end

So you need to add name: to your route, so this should work:

stagers_stager_croppable_image_path(name: 'profile_photo')

However, since you are not using a specific route name on that each loop, calling it with name set to cover_photo will not work. I think you probably want to use a regex like

constraints: { name: /(cover|profile)_photo/ }

Try declaring your routes like this (sorry I messed up your style)

Rails.application.routes.draw do
  namespace :stagers, path: 'stager' do
    resource(:stager, path: 'profile', only: %i[edit update], path_names: { edit: '' }) do
      resources(
        :croppable_image,
        controller: '/croppable_images',
        path: '',
        param: :name,
        only: %i[edit update],
        path_names: {
          edit: ''
        },
        defaults: {
          record_type: 'Stager'
        },
        constraints: {
          name: /(cover|profile)_photo/
        }
      )
    end
  end
end
