Cannot complete onboarding using custom provider

Just installed Bolt AI 2, and greeted with a “Connect a Provider” which shows SetApp or Bring Your Own Provider. I want to use oMLX, so I select bring your own and enter its details, accept the default listing of all models… and arrive back at the “Connect a Provider” screen.

I don’t want (nay, am not allowed) to use a remote provider as I’m on a work system.
