This is "fixed" by 5d7dca16af4f4cb049f1f573f6c5eefd8b427fc0 (the not crashing part).

Hard to fix "properly" without that core patch but there is a workaround for this issue:

Create a custom controller context for Term Customizer

# frozen_string_literal: true

# lib/term_customizer_custom_controller_context.rb
class TermCustomizerCustomControllerContext < Decidim::TermCustomizer::Context::ControllerContext
  def resolve!
    env = data[:headers].env
    controller = env["action_controller.instance"]

    @organization = env["decidim.current_organization"]

    if controller.respond_to?(:current_consultation)
      consultation = controller.send(:current_consultation)

      @space = consultation
      @component = env["decidim.current_component"]

      return
    end

    super
  end
end

Apply that to Term Customizer

# config/initializers/term_customizer.rb

require "term_customizer_custom_controller_context"
Decidim::TermCustomizer.controller_context_class = TermCustomizerCustomControllerContext
