App deploys stuck on "vN is being deployed" - cannot update app

I am unable to update an existing app via a registry.fly.io image. New deploys don’t make any progress past the vN is being deployed stage. I have attempted 5 deploys - v19-v25 - over the last 24h with the same end-result.

What should I do next?

FWIW: I am able to pull & run these images locally.

Deleting the app & re-creating it fixed my issue:
