Problem with Jumpstart:Module config (Jumpstart.config undefined)

I just git pulled the latest Jumpstart commits (it's been awhile) to my app (Rails 6) and am attempting to merge everything and move to Rails 7, etc. I've merged all the conflicts but am getting the following error when trying to run the rails server:

/config/initializers/devise.rb:39:in `block in <main>': undefined method `config' for Jumpstart:Module (NoMethodError)
config.mailer_sender = Jumpstart.config.default_from_email

I'm not sure how to test/reset/fix the Jumpstart configuration to get it to be recognized. Any help would be appreciated.
