Ruby 2.7 sounds like nightly which has dropped support for Passenger. Why dynflow won’t start isn’t answered by that, but we need more complete logs to really understand why it’s failing.

It would be good if you used code tags when pasting data that shouldn’t be formatted. That makes it more readable.
