Getting a list of enums broken on ruby 3.2.2

I just updated my rails app from ruby 2.7.0 to 3.2.2 and a following code:

class TemplateField < ApplicationRecord
  enum group: {
    'primary':    'primary',
    'secondary':  'secondary',
    'auxiliary':  'auxiliary',
    'header':     'header',
    'back':       'back',
    'unassigned': 'unassigned'
  }
end

class Template < ApplicationRecord
  TemplateField.groups.each do |_key, val|
    has_many "fields_#{val.pluralize}".to_sym #...
  end
end

Broke with a following message:

NoMethodError:
  undefined method `groups' for TemplateField:Class

Basically, also calling TemplateField.groups directly in console produces the same error. Does anything changed between ruby 2.7 and 3.2 that I should be aware of?

In my particular case, that was caused by outdated sorbet-rails dependency. Running bundle update sorbet sorbet-rails fixed the issue for me.
